Pressure Sore at 13 Weeks

After 3 Weeks of Treatment – 10 minutes, twice a week

After 6 Weeks of Treatment – 10 minutes, twice a week








Coherent photons, which are particles of electromagnetic energy, are emitted from an infrared cold laser (also referred to as low level laser, soft laser or therapeutic laser). These particles enter the tissues and are absorbed in the mitochondria – which are tiny structures within the substance of each individual cell. The energy is converted to chemical energy within the cell.

The permeability of the cell membrane then changes, which in turn produces various physiological effects. These physiological changes affect a variety of cell types including macrophages, fibroblasts, endothelial cells and mast cells, resulting in wound healing, pain relief, reduced inflammation, drainage, etc.

When comparing lasers, two measurements are key. The first is the wavelength, which determines the color of the light and is measured in nanometers (nm). The second classification is the power of the laser, which is measured in milliwatts (mW). A laser of 500 mW or less is classified as a Category 3, cold laser. This means there is no danger of burning the skin or tissues, or causing damage from overheating. Lasers that are stronger than 500 mW are classified as Category 4 lasers and these should only be used by professionals, or in conjunction with a device that monitors the temperature of the tissue during exposure.

Another defining characteristic of laser light is that it is coherent light. This means that if you shine the light against the wall and then you back up farther and farther away, the laser point will stay the same size. If you happen to have a laser pen that is just an LED, then as you back away the light will fan out – this is the quick way to tell the difference between the two.

Simple colored laser lights have an affinity for the same color. For example, if you set up a green balloon that has a red balloon inflated inside it, and then you shine a red laser light on the balloons, the red balloon inside will pop, but the green one will stay intact. This is because the red laser has an affinity for the red balloon only.

However, infrared lasers are “colorblind” so they will penetrate deeply into tissue. An infrared laser light needs to be a minimum of 650 nm and 5 mW – at this strength it will penetrate almost half an inch into the skin. So if you have a shallow wound or an abscess, this strength is probably sufficient and infrared laser pen lights of this strength can be purchased fairly inexpensively.

After 6 Weeks of Vetrolaser Use

After 6 Weeks of Vetrolaser Use

If you have a deeper wound or a fistula, then you may want to invest in an infrared laser that can penetrate deeper into the tissue. Unfortunately, these infrared lasers can be very expensive. The ones I found ranged from $1,200 – $13,000. How many people suffering from fistulas are likely to be able to afford that? So I went “outside the box” and I found an infrared laser – called the Vetrolaser II – that is sold for animal-use, for only $525. This is exactly the same quality, technology and strength of the expensive human-use lasers. It has three 808 nm diodes (lasers) in one unit, at a strength of 200 mW. Thus it can penetrate two inches when used on Caucasian skin (darker skin results in less penetration).

To sell or advertise a laser for human use, you have to submit it to the FDA and get approval – this is possibly the cause of the high price tag on human-use lasers. But if you specify that it is for animal use only, then you can avoid the FDA process.

I spoke with Dr. Daniel Kamen D.C, who sells this “veterinary laser” and he said that the ideal way to use the laser (to get the fastest results) is to put the laser directly in contact with dry skin. However, if the skin is wet, or the wound is open, then you need to hold it off the skin to avoid wetting the laser, but hold it as close as you can.

It’s worthwhile to note Amy Spiegel’s article about healing her son’s peri-anal abscess: She used an infrared laser pen light and the healing took six months when used for 1-2 minutes per day. We couldn’t get any information about the wavelength and power of the laser she used. But I did find a photo that looked just like it and the seller said that whilst the laser was 635 nm, it was less than 5 mW in power. So this is perhaps why her son’s abscess took so long to heal.

Interestingly the infrared laser pad Amy’s son is using now (for maintenance) contains 50 diodes (infrared lights) of 880 nm and 100mW for each diode – which a lot stronger than the pen light used to heal the fistula (and, at $844, is a lot more expensive).

Below are some places to purchase therapeutic-quality lasers at the cheapest prices I could find. And, as per usual, if you try this therapy, please let me know how it worked in the COMMENTS section below.

Infrared Laser Sources

Red Laser Pen (635 nm, 5 mW, 1/2″ penetration) – has a button you need to press and hold down, which personally I don’t recommend as it gets very tiring. However, if price is an issue, then this is a good option at $69.95 since it also includes a case and about 14 disposable tips in varying sizes. Good red laser pen of same strength as the professional one – just with less attachments and does not have an on/off switch that stays in position – must be held down continuously.

Doctors Red Laser (635 nm, 5 mW, 1/2″ penetration) – has on/off switch and comes with a wide variety of tips, both straight and angled (for dental applications) and a padded travel case. Useful for treating thinning or receding gums or gingivitis. This professional red laser is a good deal for $149

Blue Laser (450 nm, 5 mW) – has on/off switch and comes with a wide variety of tips, both straight and angled (for dental applications) and a padded travel case for $219. Tips can be interchanged with the Doctors Red Laser as using the two lasers in combination can work well for stubborn cases. The Blue Laser has been documented to help the body’s defenses eliminate bacteria or other infections. (With a photochemical effect). For this reason, if your fistula has a lot of infection, this blue laser may work better than the red ones.  It is also better for treating (softening, dissolving) scar tissue. Good for oral treatment of gingivalis. This company used to carry a Violet Laser, but switched to this blue one because, “At the cellular level it stimulates the cytrochomes. Most effective for Propionibacterium Acne and most skin conditions. This wavelength has a broader spectrum for killing bacteria than violet.”

These three lasers are all sold by Dr. John Schimmel – who specializes in acupuncture applications. However, he has 30 years experience and countless seminars on laser therapy under his belt, so is very informative to speak with on many applications/problems. You can contact him via his site, or phone 719-201-8581

Vetrolaser II – Triple Diode Infrared Laser (3 x 808 nm, 200 mW, 2″ penetration)

This is the “veterinary-use” laser I wrote about above and it currently retails for $525.

Tel: 1-800-742-8433 and Dr. Kamen can answer any questions you might have.

Infrared Laser Pad (8 rows of 660 nm, 7 rows of 880 nm)- I recently found this very reasonably priced laser pad on Amazon, but it doesn’t list the mW. Still, since it is at 660 nm and 800 nm, it can do the job and would likely be more powerful than the laser pens.

You can also custom-order the exact type of laser pad you want at a VERY good price from

How Does Infrared Light Therapy Work?

  • This sounds really exciting for Steven, who has had his abscess for at least 5 years, and another for a couple of years.
    The Vetrolaser website mentions the safety glasses which are also expensive. Do you think this is essential. I guess we need to protect our eyes!
    Thanks for staying at the forefront Jini!

  • People keep recommending another light therapy which is not laser. Have you heard of that and is it any good?
    Best wishes,

  • Hi Jini. After reading this article, I purchased the vetrolaser to help heal my fistula. I’m wondering what you think would be the best treatment to apply to the skin prior to using the laser. Amy used ITIRES ointment and Notatum drops but I’ve also read where you have recommended DMSO and Oil of Oregano. Any suggestion would be helpful. Thanks!

  • Amy was also using the wild oregano oil. So I’m thinking you could start with that (start with 6:1 dilution and make it stronger if you can tolerate it). If that’s not working well enough, then you could add some 70% DMSO to the mixture. And in that case, I would be prepared to follow treatment with aloe vera if necessary – the fresh plant is the best – just cut off a small piece from the end of a leaf, split it open with a knife and apply directly (say thank you to the plant for sharing its healing) in case the DMSO leads to skin irritation. Oy vey, I’m not supposed to be “giving advice” over the blog, but what can we do?

  • i would love to know as well if there are any doctors that are willing to treat with the laser. Jini, do you have any info on that?
    I have a perianal fistula with a drainage seton in place.

  • Nice post!!!!! Thanks a lot. I am very greatful to you for posting the whole working of the infrared light therapy. I suggest my students to use this therapy in lab as they are working on the body skin of animals.

  • What info can you share about infrared and scar tissue? We take our daughter to a Dr. who uses infrared light as well as other treatments but sometimes only infrared. It can take weeks/months to get an appointment. I do other therapies at home and believe the infrared and/or accupunture helps her the most . I would like to purchase and infrared tool, but not sure which would be the best for a small child with over half her back with scar tissue.

  • Well, I am certainly no expert in this field, but from what I’ve seen, it looks like the violet laser is better for breaking down scar tissue than the infrared. However, have you looked into DMSO for treating scar tissue? It was first used in the 60’s with burn patients. Then the FDA got involved and banned it for everything but interstitial cystitis (for which a drug co. owns the patent of course) – so this amazing substance got sidelined.

    Go over to the Tahoma Clinic blog and read Dr. Wright’s stuff on DMSO – he also sells a great book about it on his site by Norman Walker. We have seen some good results using DMSO for scar tissue thus far and I’m also experimenting mixing DMSO gel with pure aloe vera gel – easier on the skin (less itchy, less rash on sensitive types, etc.). Good luck and please post here again with your trials and results…

  • hi jini. . i know this post is old. . . hopefully you get this. . . thank you for the info here. . . ive been doing a lot of research in the past couple days as to the viability of laser therapies to potentially aid in healing cartilage. . . my injured meniscus in particular. . . . . . ive been reading about NeHe lasers and GaA / GaA1A lasers. . . with varying powers measured in nm’s . . . . . .

    ive found this site which sells all sorts of lasers. . none of which are promoted for healing purposes but have very detailed specifics as to nm’s and mW’s . . . . and they have some very good prices. . . im curious about acquiring something in the 900nm / 300-500mW range. . . .

    do you know if the numbers of potency in regards to lasers are equally beneficial when using different types such as NeHe / GaA / GaA1A / solid state?. .

    ive emailed the company to see what they actually use as the site does not say. . .

    anyhow. . . any info is helpful. . . thx so much. . . .


  • JUSTIN – Whew, you’ve gone beyond my knowledge with this one! Best would be to phone both of the docs (their phone numbers are listed in the blog post) and ask them these exact same questions. I suggest asking both since then you can compare answers and possibly glean the best info.

    Please let us know what you find out!

  • Hi. Has anyone ever used the vetrolaser for healing disc herniations? I’m currently seeing a massage therapist who is treating me with the TerraQuant Pro but its getting pricey to see him twice a week and his model sells for $3995. My son also suffers from muscle spasms (upper back) and acne and thought if the vetrolaser worked it would be a god send for us both.


  • Hello,

    Would a laser which is mounted on a gun for aiming have the same effect, since it has a distance of 2000m. There are red and green. Any feedback on this? I was planning on putting in close to the skin to loosen fibrous tissue.

  • Opennes – to find out if a laser is strong enough and/or safe, you need to find out the nanometers and milliwatts of the laser and do NOT use a laser that is above 500mW.

    To have a healing effect, the laser has to be at least 635 nm, 5 mW.

  • Hello

    Does this mean that the power(mW) is not as important as the wavelength(nm). Love your article BTW. I saw a scalar wave product on the market. But its too expensive(3k). Later I tried contacting Thor. Bad customer service.

  • as long as it is 5 mW (which is very low power, think of a lightbulb at 40 or 100 watts) it is powerful enough. See the end of the post again (above) as I have added a link to another laser I found on Amazon that looks very good for a very reasonable price: Infrared Laser Pad (8 rows of 660 nm, 7 rows of 880 nm)

  • I used to recommend my patients go to Staples for their laser pointer for $25 BUT RECENTLY FOUND A LASER FLASHLIGHT AT NAPA AUTO. I RECOMMEND MY PATIENTS BUY TWO TO CUT TREATMENT TIME IN HALF, 2MIN PER POINT.

  • I have found violet lasers which are much more high powered than the one you reccomend, and they are only $50 – $80. How can this be? They certainly dont look as nice as the one you reccomended, they look like very simple pointer pens without the different heads, but essentially, It is the power of the laser we should be paying for? I really need some help as i desperatly need to do some laser therapy on a reoccuring abscess.

  • Hi,

    I’m experimenting with the Doctors red laser and am thinking of trying the Violet laser too as I work on healing a perianal fistula. I see that Amy was using hers for 1-2 min per night and that it was less powerful than the Doctors red laser. I see that the pressure sore at the start of this article was treated for 10 min 2x per week with a laser of unspecified power. The instructions that come with the Doctors red laser say treatment should last 1-3 min.

    Any idea what a maximum safe dose/frequency of treatment might be for the Doctors Red laser and/or the violet laser? I see that it falls within the Category 3 “cold” type of laser and is at no danger of burning or overheating the skin. Does that mean that there is no safe maximum exposure limit? You can just use it as much as you want?



  • Hi Garth, I used the exact same Doctors red laser to treat a tear in my gum tissue and I used it for 10-15 minutes, once per day.

    I have no idea what the upper limit would be… let us know your experiments/results! And stay connected to your gut intuition.

  • Thanks Jini!,

    So far I’ve used the laser on 4 spots in the fistula/abcess area at 3 minutes each in combination with your oil of oregano/olive oil protocol and an oral homeopathic remedy. Yesterday I performed my infrared routine three times and there are no noticeable negative effects today. Hopefully, it’ll help heal this fistula. It seems a little better today but it’s too early to be sure. I’ve had it for 2 years and it flared rather badly recently. I’ll let you know what happens. Thanks for your feedback.



  • Hi Jini,

    I found some additional information on the infrared laser pad from Light Therapy Essentials’ website (

    “This LED array is set up so you can operate
    the red and infrared leds separately or together.
    You can select which ones you want to use with the two switches.
    It has 120 LEDs – 8 rows of 8 LEDs each of the 660 red, and 7 rows of 8 LEDs of the 880 infrared. The 64 Red 660nm LEDs put out 4000 mcd each
    The 56 Infrared 880nm LEDs put out about 6.4 mw each
    Comes with a 12 volt power supply.”

  • I am perusing your site for the first time and just bought your ebook and look forward to reading it. I have Crohn’s and an anal fistula. No sign of Crohn’s on an ultrasound a week ago (yay) but the fistula just closed up and became a painful abscess. Had to go to the ER, after waiting for about 10 painful days for it to drain on its own. No go, despite plentiful sitz baths. They don’t know why they close up. One thing that jumped out at me from the comments was that some of the people mentioned getting these nasty fistulas after having a colonoscopy. I did a little research and others on the internet are wondering about this connection, since they didn’t have one before a colonoscopy. Wonder if there is a connection. It wouldn’t surprise me at all. Of course, this would be denied by the medical community. Sadly, there is big money in colonoscopies.

  • hello Jini i want to now what kind off protocol , routine is the best for fistula in case off vetro laser im alraedy on wild oregano protocol and just got the laser

  • Dear Jini,

    First, thank you for the wonderful work that you are doing!

    I have hemmorhoids and one of them, which is an internal hemmorhoid, has gotten quite large. It bleeds, especially when irritated, and it sits in the middle of the anal opening, preventing the sphincter from closing properly. Thus, I constantly have a mucousy fluid leakage. I was told to have surgery by a colorectal doctor but am looking for an alternative treatment.

    I came across info on the Vetrolaser and wondered if it could be used to treat hemmorhoids. Then, I read your article where you talk about lasers, mentioning the Vetrolaser. Do you sell this?

    Any info would be very much appreciated.

    Thank you!

    1. Hi Adrianne,

      We don’t have any experience with laser treatment being used for hemorrhoids (and we don’t carry any laser products, unfortunately) so we’d love to hear about your results if you decide to try it. If you aren’t pleased with the results, Jini developed a protocol specifically for hemorrhoids which you can read all about at this link:

  • I have used the vetrolaser very successfully for joint pain. I saw that someone asked about using the laser for cancer. Do not do this. Lasers are contraindicated for cancer, because they can cause (cancer) cells to grow.

  • Wow, very interesting site. I stumbled on this site after researching the Vetrolaser for use on my horse’s swollen tendon and my boyfriends herniated discs. I haven’t purchased it yet, and was hoping for more reviews on the laser. It seems like a decent investment for the amount of power. It is amazing what these things can do! Regarding the most recent comment on using it for cancer, that is a no no from what I have heard. A laser should never be put on a tumor, the brain, or the uterus. All can have severe negative effects. If I order the Vetrolaser, I will post any other instructions that might be relevant for this site. Good luck to all of you, some of these ailments must be extremely painful.

    1. Hi Sara,

      Thanks for taking the time to write in. We’d love how the laser treatment works out for your boyfriend and your horse if you decide to purchase one. By the way, Jini also has a horse blog which may be of interest to you. You can check it out at the link below:

  • Thanks for all the info. I have been struggling with a fistula for a few months. Challenging to eliminate drainage.

    Will the Vet laser help with the infection also? Is there any risk of harm to the uterus being in the vicinity, since we would be using for an anal fistula?
    Could you please repost the link to the infrared laser pad on amazon? Seems it would be easier to use than the pens

  • Sara can you say more about lasers and their use on uterus’ causing problems? I’ve been using it over my pubic bone and coccyx for various reasons and of course it’s all in the same area…
    Also, Jini, can you say why or how oregano oil, a strong antibacterial, etc., has the ability to heal tissue, specifically while on either side of a rectovag fistula? Hoping with all I am that it works, after breaking my coccyx in January of this year it’s been a long slow road to regaining my health. This fisula (which also showed up after colonoscopy in July) and really intense leaky gut seem like the “last pieces” of the puzzle.

    1. Hi Liana,

      Wild oregano oil fights the infection so that the tissue can heal itself. But it is also anti-inflammatory and used to speed healing for burn patients – we don’t know the exact mechanisms for the healing though. For more details about healing your rectovaginal fistula naturally, make sure to check out Jini’s page for that if you haven’t already:

      Customer Care

    2. I know this post is old, but I have been just diagnosed with a rectovaginal fistula and was interested in seeing how your experience was. Did you use the rectovaginal fistula protocol? Laser treatment? Any information would be more than helpful and appreciated.

  • I have had my vetlase for about 5 months now and have used it on myself more than my horse. Keep in mind, it is meant to increase blood flow/circulation which causes healing, so if increased blood circulation will not help your problem, the vetlase will probably not help. I have used it successfully on:
    -pulled tendons on my horse,
    -sore back muscles on a horse
    -my own sore back muscles
    -Sore muscles in general, (do it before bed and wake up feeling much better)
    -husbands herniated disc,
    -torn ligament on bottom of foot
    -open wounds
    -bruising (not sure if there was much to gain from this)
    -Wrist pain
    -knee pain
    I hope this helps you determine whether or not to make the investment. I don’t know much about the how or why it works, and I am not a medical professional, just a person that bought a horse laser to treat myself and my horses.

    Someone asked about using it on the uterus. I would not use this on any organs, mostly because if there is a tumor or cyst of some type, this could stimulate growth for it (that is what was explained to me). So I stick with limbs and muscles. Also, it only penetrates 2 inches deep below the surface of the skin. Good luck!


  • So I came across your post I’m looking for a red light therapy for my dog which is suffering from arthritis in both back legs as well as a broken acl. We’re have taken her to the vet and she is getting laser therapy there which when she gets it done she puts weight on her leg with the broken acl!! I looked on YouTube and found some people that use a laser pen which is $600 or more (not in the budget) I looked at your links and then this came up on the suggestions:

    Just wondering if you would recommend this? my mother also suffers from arthritis and my father with lower back pain thinking about getting them one as well if you think it would help, in this case all 3 of them? 🙂 hoping to hear from you since I see this post has gotten quite a few comments over the years!

    1. Hi Noemi,

      That unit seems similar to the one that Jini’ mentions at the bottom of the blog post but with a much smaller array of LEDs. We cannot recommend it as we do not have experience with using it but the power and wavelength appear to be at good levels. Let us know how it works out for you if you decide to give it a go!

  • Justin, Jini
    Is there any risk associated with using these laser pads? Does this one provide antibacterial effect? Is there any concern of it closing external hole of fistula before internal? I was thinking of trying it for a horseshoe fistula that unfortunately goes through the muscle.

    I have non cutting setons in… Wonder how the lasers works with those

    1. Hi Amitha,

      Any benefits gained from their use won’t happen overnight. Thus, you would be able to see gradual effects if you see any effect at all. Regarding risks, that’s a question you would need to ask your doctor as we aren’t qualified to speculate.

  • Wouldn’t you know, I found this blog of Jini’s just after purchasing 2 small, hand held, cell phone sized, LED therapeutic lights from . I will see how they work for me. One is a blue array, 465-470nm LEDs, 40 mw/cm2. The other is Dual 660 RED / 850 Infrared.Array With total 120 LEDS 64 red LEDs, 56 infrared LEDs. I have a pre-sacral abscess with fistula to the colon. I have had it since 2011, at least & have had two surgeries, but it is still with me. Now, I have osteomyelitis (bone infection) of the sacrum also. That was not diagnosed immediately either. Most doctors insist I get another surgery immediately, but I am outwardly quite healthy. That is not to say I do not have impaired colon function and pain. I do, but I am using alternative therapies and diet, many things I have learned here, to keep my life somewhat “normal”. I write this while enduring the loud hissing inside an O2 chamber, which I am blessed to be able to use daily.

    I should have known to check Jini’s site first for info before purchasing the lights, but, hopefully, the two I have bought will prove quite useful. My naturopath recommended them as an option when I asked about near infrared. I will try to remember to write an update in a few months when I have an idea of their effectiveness.

    1. Hello Sue,

      Thank you for the information. We would love to hear how they end up working out for you, please update us later. Hope you continue to feel well.

  • Please correct me if I’m wrong: the led array lights that are sold at seem to be led lights rather than laser lights. I’m not an expert, but if that’s the case, I would expect the penetration to be less than laser light arrays.


    Thomas Robinson

  • Hi Thomas – i went to the site and they also talk about infrared laser therapy… so not sure how/why they’re using the different terminology.

    I think as long as the seller is reputable – i.e. what they’re claiming IS actually what they’re selling. And the light/laser conforms to this:

    “An infrared laser light needs to be a minimum of 650 nm and 5 mW – at this strength it will penetrate almost half an inch into the skin.”

    Then it should be fine.

    1. yeah i just bought a red/blue light pad from theLEDman and now i’m concerned it’s going to be another waste of money.. they’re definitely LED’s and not lasers, will that still work? there’s definitely no reference to Lasers on the website that i could find… also trying the oregano protocol, along with the DMSO/oregano/colloidal silver etc syringing… unfortunately, my abscess never exits my body to drain, just gets bigger and bigger and wraps around my colon and hurts like h… 🙁

  • Hi Jini,
    First thank you for writing your book!!! You have been a life saver!! I was diagnosed with diverticulitis earlier this year. My 3rd attack lead me to you and I have been following your advice ever since. The oregano protocol has helped tremendously!
    I have a question I own the vetrolaser- do you think it would help to treat the diverticula- I get twinges – over the holidays I was afraid of an attack – I am drinking absorb plus – which is helping too!

    Any thoughts on strengthening diverticula with cold laser?

    Thank you again!!

    1. Hi,

      I have a question with infrared laser or blue laser,
      Can we apply on the vagina for a rectovaginal fistula. Fistula is 1.6 cm in depth
      Laser is of less than 650 nm and 5 mW.

      Will it burn and scar the vagina.
      I am desperate to try because WOO doesn’t seem to help even at full strength.
      Some how I am not comfortable using DMSO.


      1. Hi Vidya,

        One of Jini’s readers has improved upon this protocol by using an infrared laser, to cause the wild oregano to penetrate more deeply and also to speed healing. Jini recommends Doctor’s Red Laser with the dental attachment – which is a thin, clear tube you can then insert into your vagina for treatment for rectovaginal fistula healing.
