DD has been getting extremely flushed in her face during workouts lately. She has always had a little trouble with this but its seems to be worse lately. Her cheeks get extremely red and sometimes her she also gets splotchy on her forehead and neck and chest. A couple of times she has goten really hot when this has happened. Her coach is making her travel around the events with her water bottle and she also set a goal for her to drink the entire bottle during practice. I am a little concerned. Sometimes her face remains red even a hour after practice. Should I be concerned?
