Hi: My wife got PD and I got the carpal tunnel syndrome, and the latter was far easier to remedy. I had difficulty with numbness and constant tingling around 8 years ago. Neurological testing and surgery, after unsuccessfully trying a mega dose of Vitamin B7, alleviated the problem. However, when similar symptoms began to appear to the other hand, my acupuncturist who was already treating me for arthritis, suggested that treatment for that problem be initiated. Lo and behold...numbness and tingling were minimized together with the other problem. Alternative medicine worked in this case...
