I've been having trouble with my left hand, arm and neck. Waking up in the most unbearable pain to the point that I can't move my arm. Pins and needles and numbness in fingers. The Doc says it's a pinched nerve, put me on anti-inflammatory, steriods and said it should improve. I'm wearing my TENS unit near all the time and it isn't improving. Does anyone have experience in this type of problem? Thanks in advance!!
