EsthersDoll - I definitely understand your anger. I too am still upset that a woman decided to hit me so hard that I went flying into the glass while playing no-check women's hockey. I was in tip top health up until that point.
I woke up this morning to find my head, neck, and left foot vibrating like crazy. It stopped as soon as I moved my body. Just don't get it. Hopefully it turns out to be something that can be easily explained.
