My wife aged 72 yrs was diagnosed having Parkinsonism 6 yrs. back nd started with a single dose of Syndopa110 (Levidopa100mg+Carbidopa 10mg). Now she takes 5 tablets per day with additional Syndopa 125 CR at night. She is not having tremors at all but during off times she experiences discomforts like arms muscle stiffness and cramps like feeling. This is often followed by spells of panic feeling. By massaging the muscles she gets some relief. the discomfort lasts for half an hr to one hour. Doctor had advised her to take different pain relievers but none of them are satisfactory. I have a feeling that Levidopa itself causes such symptoms. I would like to know whether anybody else had experienced such symptoms.
