I have forearm weakness and psp. If I grab a gallon of milk it hurts my forearms. I can sense that I am losing my forearm strength. I used to be pretty strong. Does anyone else have this symptom? The pspaustrailian site list Fasciculations (small ripples or spasms visible under the skin) and Muscle Wasting (Limbs) as symptoms but many of the other websites do not list it. Progressive Supranuclear Palsy and Muscle Wasting?
