To Lady4321 - my good friend used to have this problem too but not just rashes, she even got sores. She tried a braliner - it fits inside a bra and keeps your skin dry so you don't have to use medicines or anything. I think she said it was called wickem. she bought in on the internet and it really helped alot. But she went to the doctor first to make sure it wasn't anything serious first. I hope this helps you.
