I bumped my head (front above hairline) HARD yesterday. We went cross country skiing for a couple of hours and I was fine. We came home, made a nice dinner, and relaxed until bedtime. This morning when I got out of bed, l lost my balance. Within a few minutes I had diarrhea, vomiting and extreme dizziness. I could not stand up. Now I am up and walking slowly, and the diarrhea and vomiting have subsided. I am still dizzy, but much less. Will this likely clear up on its own? YYYY@YYYY
