Hi, I have had this(RSD) since my butt(coccyx) hit the cement. My life changed instantly with sweating cold sweats that would makeme freeze and my body, head and the world spin, till I threw up. Drenching my clothes where I stand or lay, sweat pouring off my hair like it's a faucet, each individual hair has it's own flow. Freezing cold feels like near death experience the more and more it happens to me. My body is freezing and is pouring sweat off of it, day in day out it never stopped until we raised my time relief pain pill to 40 mg, and then that's when I felt relief from the pain in my neck, back and feet. I was on the 40 mg for a few years like 3 or 4 before raising again to get the same relief. I now am on 80 mg and feel relief from the sweating as I sit and type, which I could not do if it was not for the pain pills.
