Again, thanks so much for your concern and help. His surgery was regular abdominal surgery. I know he is depressed but will never take anything for that. His Mom had severe mental health problems and he doesn't want to take ANY medicine that is directly or indirectly related to helping the brain. We have walked two days now and so far he hasn't seen any relief. But we will keep on trying. His appointment with his neurologist is tomorrow and I know he will remind Charlie what walking will do for his Parkinson's.
