Last August, out of the blue I started to have sensations through my body. I couldn’t sleep. It is hard to explain. I had to stand. Sitting it laying was difficult for anything more than a few minutes. I have had lots of tests and no one can tell me what caused it. I was prescribed zymbalta. I don’t know if it helped or my issue have gotten better. The sensations are still there but now it is tolerable. I wear loose fitting clothes.
