Chris, I think you've solved the mystery of my double vision........another PD symptom. Dr. Abe had a post on this as problems with eye muscles not functioning properly. I wear progressive lenses and am also so plagued with runny eyes, altho I understand with PD it's usually dry eyes. Also cannot clear my throat and have choked several times.
