I am a new member here. Just to tell a bit about myself, I am 13 years old. I have had RSD for about 5 years now. Once when I had a nerve block done, my leg was twitching so badly that I couldn't sleep. I couldn't even sit down because I would fall out of my chair! My ankle would also twitch a lot. This was actually a good thing, even though it hurt a lot, because shortly after I started to get better.
