I am a white female, 29, 150 lbs, 5 3 and I tend to drink heavily every night. For about two weeks now I have been having a bizarre and alarming problem. It feels like spontaneously my nerves turn on overdrive, like in my brain , and neck, and sometimes all over. It happens mostly from mundane sensations or sounds, like the sounds of moving my computer mouse, or scratching my arm. I almost feel like it s going to zap my brain, if that makes sense. Could this be a sign of a stroke some kind of condition?
