Hello K__,
I have been zapping for 5 days straight, 7 min on with 20 min breaks in-between. I did not feel tingling/numbness until last night. It is only my left arm. My arm kept tingling on and off for most of the night (which kept me awake most of the night). Is this normal? Am I doing something wrong? I also want to note that I've never felt better, no more back pain. Besides the tingling, this is a wonderful device!
Thanks, Electra Nov. 5, 2007
