My daughter was diagnosed in february and the biopsy showed minimal change disease. SHe was started on 80 mg of Prednisonse for 2 months, has been reduced down to 40 and if she is protien free at the end of May will be reduced to 20 mg. she has had lots of side effects with the Prednisonse. My quesiton is does anyone else have a teenager with this and if so what kind of information have you been able to obtain about intense exercise. She is wanting to join the cross country team at school, intense training , 3 hours 5 days a week. I am afraid this will trigger a flare up. Any comments?
