Recently, I joined a softball team for
the first time in 5 years.
The first practice that we had, we stretched, ran to
the fence and back, and then threw the ball back and forth. Immediately following throwing, I felt very light-headed and sick to my stomach. I ended up vomiting. After sitting down for a bit, I felt much better and was fine for the rest of the day apart from getting very out of breath(I have asthma which I don't take medicine for, so this was not surprising).
