I am taking medication that unfortunately attacks the collagen in the skin of my feet. They were getting worse and worse and after each dose the infected circles grew. They were so itchy that they woke me up at night. I treated the worse one with the Ray gun, and for control left the other untreated. Once a day. I swiped it over the feet for a few minutes. It’s a large area. The itching on the treated foot immediately stopped, the other foot continued. After 2 treatments in 2 days, I just gave up on the control test and treated the right foot as well. The itching stopped as well. Then the dead skin started to peel off, and the infected circles disappeared. After 4 treatments, the infected circles stopped growing, the skin as an almost even tone, still darker, but not purple as it used to be. I was given steroids to stop this before. But they didn’t work. This is a very big deal.
