Ohh wow!!! that is VERY sore!!!

You must be so uncomfortable!
have you tried sudocream? E45? tea tree based creams? or aveeno?
I used to have it under my bust and now it is clear, i do not know if it via my diet, or the creams I have been slapping on or my vitamins......probably a mixture of them all, but it is bloody sore when your bra rubs on it eh??
Have you tried Trimovate or are you keeping away from steroids?
