No it's not dirty
Basically when i get hot (only has to be a slight rise in temperature) i get a really REALLY REALLY itchy back and chest. There's no signs to show that there might be a rash it just itches like crazy, i can't explain how itchy it gets (depends on how hot i get). Not sure what it is though, i'm not on any medication for anything else and my diet is pretty well maintained. I thought it could be stress related but i haven't got any grey hairs yet
Any ideas on what it might be? It's quite annoying, there's no chance i can get any fitness in with this problem
