Hello. My name is, Michael and I am 29, 5 8, 190lbs, generalized anxiety disorder. Pinched nerve in my neck and a bulging disk, mild central canal stenosis in lumbar area with a couple disc herniations in lumbar area. I have strange question (I haven t asked my family dr. yet, because it sounds kind of strange)...sometimes I get what seems like a static electricity sensation on top of my head (kind of like when one rubs a balloon on top of his or her head), and also this strange deep itch sensation on the same part of my left back (it will last a few days, then go away for a few weeks, then return)...I was thinking that maybe it was just an itch, but when it happens, it s always in the same part of my back and top of my head.
