My mother Joyce (70, striatonigral degeneration) is experiencing terrific pain in her left arm -- the one affected by the disease. Normally, the arm is very rigid, but lately it's been painful, too. While in the hopital for hip surgery she had them x-ray the elbow, where the pain is greatest, but they found nothing. She describes the pain as a knot -- and think stress makes it worse. She's tried Tylenol. Tonight she's applying moist heat. I have two questions: First, does anyone see any reason why heat would be bad for this? Second, does anyone else experience this knot-type pain in an area affected by the disease? If so, any tips for dealing with it? As always, thanks in advance. Debbie White [log in to unmask]
