About a month ago, I got a rash over my chest/arms the day after a national judo squad training session. I assumed that it was some kind of gi-burn. After a week I went to the GP and he said it wasn't a gi-rash (I'm still pretty sure it is) and gave me some cream which didn't work.
Basically my question is how long do gi burns generally take to clear up, and what's the best way to deal with them? I'm still training and it flares up after judo sessions.
