My husband, who has PD for 8 years, for 2 months now has had a weak right ankle. Coupled with his shuffling of his left feet and his problem with balance, both due to PD, the ankle is creating havoc with his walking. His neurologist says it's due to a pinched nerve. Also sinemet relieves all his PD symptons, but weakness still persists in the ankle. He does not feel any pain in his back or his leg. Does anyone have experience with this kind of thing? Helen
