I found that I had to use a cloth breast pad between my breasts to help keep them dry and drying off the area with a hair dryer after a shower. Go to the Dr and just check that there is nothing else going on, such as thrush, which could be keeping the area irritated, if so something like Kenacomb ointment might help (anti-fungal with anti-inflammatory). If you use a wash puff (whatever they are called), I would suggest stopping, I found that if I used one it made it worse, even a new one didn't help. HTH
