Scott:
I've had this problem for years, It stops when I give the hands a rest for a day or too. Asked my doctor, he was sizing me up for a bypass or something, but could find nothing wrong. I think the over use of the hands causes the muscles to tense up and cut off the circulation, causing numbness and tingling sensation. I play guitar and really give em a workout on the keys too.
When I play guitar the left hand goes, keyboards right hand. Its hell getting old.
You should visit your doctor just to be on the safe size, could be your getting a warning signal?........Pose
