Update: Called in to work. Could not sleep more than an hour. In bed I thought my body was a red chile without the top, and I was doing a wavy motion. So I got up and was posting here. Then, I thought, I'll get some more water. I couldn't stand, legs a meter apart and could not orientate myself in the room, nearly falling over. This lasted an hour. It is much better now but I am going to the ER. Thank you for the information. I even packed a bag. I am officially scared. That is a brain thing, because it was my legs, not torso and arms. I really have messed my future health here. So, calling a cab.
