Yesterday I was in so much pain that I decided to sit in a hot tub for a while, about 15 minutes. Afterward I sat in a steam room for about 5. I felt better for about a half hour or so but it knocked me out for the rest of the day. I had to spend the day in bed because I couldn't move! This happens to me a lot when I get massages, too. I've read a lot about both of these treatments releasing built up toxins in the body, which can make you feel drained at first but a lot better after a while. I'm assuming this is what happened. I feel better today but not 100 percent. Anyone else had this happen?
