Hello,
I have symptoms som much like yours. I havent been able to go to the doctor due to insurance problems. I have the twitching all the time. Inside my body and out. My legs, and my arms ache, and they twitch. My hands are the worse, and then my head. I have heard a lot of people say that is sounds like either Ms, or fibromyalgia.
I am also afraid, and very confused. How did yours start out? And are you feeling worse?
