On Friday, I was at a concert, and someone threw a bottle at my head. It didn't hurt at the time, but Tuesday I started getting this weird dizziness, and nausea. I haven't been sick but, every morning around this time, I get a sudden headache. My temple feels like it's being stabbed on the left side, and sometime my neck even hurts. It comes and goes but, yesterday I realized there was a small bump behind my ear too.
