My daughter suffered heat exhaustion a couple of weeks ago, she was pale unable to walk and passed out. we went back to dr yesterday for follow up and he has run blood work we are waiting for results. Tonight she ran another XC meet 5K and came across pale face and blue lips and she felt like passing out again. She is asthmatic however I am concerned there could be something more going on. I will call dr in am and let him know another episode happened. My question is do you think her ADHD meds could be causing these episodes. She has been on them 3 years and has been running 2 seasons.
