I also feel what I describe as "jolts" to my neck, like electricity or like someone hit you. My intestines move so hard and make noises when I'm not hungry. I feel things crawl in my skin and especially my muscles go crazy like they are trying to spasm or they just go crazy and move in one spot for about 20-30 minutes. I zap too and take all kinds of goodies. This especially happens to me when I first take my natural meds. It's the lyme or the mycrofilarial worms, that's what I think. I'm feeling better doing cats claw, vit.c and zapping.
