I think I've been having seizures. I have been having what looks like severe chills/shivers accept I'm not cold and I don't have a fever. My whole upper body shakes/moves uncontrollably for a few seconds. I'm conscious I guess but at the same time when I have it I can't control it and I kind of have to drop everything when it happens. I'm sorry this probably doesn't make sense. I could be wrong though. It might be the medications I'm on.
