As per the tingling.. I often have this in my arms, ahoulders and sometimes even neck. My doctor has told me that the tingling, in my case, is related to a pinched nerve I have in my back. I mistook it for panick symptoms, as a long time sufferer myself, and even once thought I was having a stroke. But the jolting sensations you're getting warrent a trip to an M.D., I think. Especially if you have tingling in your face. I hope this helps. Feel free to e-mail me about your progress.
