Oh Pat!!! I don't know how I missed this post!!!!!!! Oh my goodness!!! You must have been embarrassed yourself, because, if anyone saw you, they must have wondered for sure what you were doing, or what was happening. I hope someone came to help you!!! I know it's not funny, but it reminded me of one of those comedies where someone gets zapped and their hair is standing on end. I believe Laurel & Hardy had something like this, and Laurel had smoke coming out of his head. I'm sure they don't have a charge strong enough to hurt you, but that had to be quite a shock when it happened!!!! Lynn Pat wrote: I have a tens story that I just gotta share. When my daughter was about 6, some twenty odd years ago, I had a nexk injury that required a TENS unit. We were in the grocery store and she bumped the control for my unit and sent it up to full strength. I started to shake and spasm like I never had before and never have since. I couldn't get my hands to work to turn it down. My daughter said to me, "Mom quite that you are embarassing me!"
