Hello, Sue and Charles, I have had pd since 1982. I must comment on Charle's uncomfortable feeling. I had a much more severe form of what i think may be related to this pain or discomfort--cramp, muscle spasm.. It may be a foirm of pd dystonia. I had it predominantly on my left side and had a palluidotomy in 1996 and my left side has been free of that problem]. On my right side, now, i have the "discomfort. I take cogentin for this problem now. It temporarily relieves this dystonic pain. Discuss this with you dr, very thoroughly. hope this helps in some wayu----pete
