Infra-red I know as good in many uses to the body. I had infra-red used on my ankles a year after a car accident I was in, and my pain was so bad I was getting to the point I couldn’t walk. I would have to ask for ANYONE to rub my ankles it was that bad. On my first treatment I got lucky and noticed a huge difference in my pain it was almost gone, I was told this was very rare to have happen specially the first treatment. I am happy to say that was about two or three years ago now and I haven’t had problems since. (Note: I have Fibromyalgia). I have heard great things about the infra-red saunas too. BUT that being said I need to do my homework on it. We were looking into buying one of those BBQ’s ourselves, but I was wondering about them too. Any thoughts on this Dr. O or anyone?
