I am 72 yrs. Old male. An year ago I used to walk 6 km. Every day in the evenings without any difficulty. But of late I am not able to walk even 3 km. Also I get out of balance very often and likely to fall down. I cannot drive two wheeler. Car I can drive with much strain. I think I am suffering from parkinson' s disease. I am taking syndopa plus 125mg half tab three times in a day half an hour before each meal. Is there any pmt. Remedy. Please advise.
