My 10 yr old daughter has started experiencing light headedness, dizziness, and shaking when playing or practicing sports. While playing soccer she breaths very heavy then hits a wall about 15 min into the game. Recently she has taken up ppitching for softball and during her lessons she sees spots, bright lights, feels like she will pass out, and becomes nausious. Our Dr thought it might be exercise induced asthma but even with the inhaler she still has these issues. Could there be something else I should have her tested for?
