I went back to work today since being off for a few days and I noticed I cannot focus on anything whatsoever. The only thing I can think of my health and what could possibly be wrong with me. My neck is sore on the left side and without thinking about it I turned my head to the side until my head was sideways. It didn't drop suddenly or anything it just turned until it was resting on my left shoulder which really freaked me out. I still for the life of me cannot get the whole body twitching to stop. A different parts of my body at different times will just twitch and then go away my legs, back, shoulders, head, eyelids, fingers, toes, etc. It doesn't last more than 2 seconds but it still is freaking me out. I don't know what I can do to stop it. Does this happen to anyone else when they're stressed or anxious or is there something serious that I should be worried about.
