About 5 months ago I was workink outon a bike ,the next day I had severe tingleing of the hands .I wento a chiro, he said I pinched a nerve in my neck. After several treatments it went away,but has been bacck off and on .It came back about three weeks ago,it is not painful,just drives me nuts ,it is in both hands sometimes in the fingers or wrist. I worry alot about this but my doctor seems to think it would not go in and out,and started after the exercise,unless it was nerve related.Please give me an opinion as soon as possible .Its driveing me nuts.
