Has anyone had an MRI? my Dr scheduled me one for this same problem. My other half thought I was weird and wasn't sure that this was a thing. This "zapping" is driving me nuts. I've been reading all these posts, (3 days) and haven't really seen anyone mention if they have any side illness. I have fibro (which i thought it was, but im not in a flare. all my other issues are related to my back. (RA, OA, DDD, etc) as I write this, I am being "zapped" seriously, why cant we find the true issue here? I'm 46 years old, and i shouldn't have to add this to my list of aliments. Anyone on medication that might trigger this? (I take 11 pills a night, 3 during the day) I'm really at a loss here and it really hurts. I/We need help!
