Marling: I know about Chalie Horses . I get them at night if I hven't stretched enough before and after swimming that day. That pain is excruciating for a moment.And one knows what to expect. The curling of the toes and twisting of the ankle into a rigid position is also painful and difficult to pull out of. I believe it is called dystonia I've read that when it occurs in the morning that it's due to lack of sufficient levodopa in the system.. But, I've also read that it is also a side effect of Sinemet. Sometimes these events pose a question, because there is another neurological condition called dystonia, per se, which is separate and apart from Parkinson's. The dystonia, per se, can occur in other parts of the body, such as head,neck, and a friend has dystonia inthe mouth which affects her speech.(She carries a small gadget which, when she inserts it along the tongue, temporarily clears her speech remarkedly.) The human body and its vagaries continue to amaze me, orshouldI say paralize me.. [log in to unmask]
