If you are talking about cold laser, yes, it has been used since the 1980s for many medical works. Newer laser spectrums, or rather, recombination of spectrums up to 1230nm, helps to take care healing, assumingly.
I have ear tinnitus as well. I counter this by wearing an earbud, with oscillating frequency to drown out the tinnitus frequency. There are many ways to do this, but to remove it completely, that is a medical mystery at the moment. There are many theories and suppression methods, but there is no known cure. Red light therapy going into 1280nm to use part of the blue light to help with exposed area, and NIR+ to penetrate bones to get to the root of the problem suppresses the tinnitus. It doesn't cure it. Tinnitus shifts and changes daily to yearly because of many reasons and conditions. Just sneezing, having a cold, having a health issues, or exposed to something and it manifests and changes. It's a phenomenon that we can't figure out yet, and we barely have a grasp over it.
I use my full BioMax 900 panel on my entire body daily, from the top of my head to the bottom of my feet, front and back. Overall, it helps to suppress the auditory changes. I use my earbud to do the rest of the suppression using low frequency shifts while listening to my published journals from various fields.
If a brotherhood is not friendly to one another, it's just a playground of bullies. We do not condone that.
