my name is Karen and my daughter has been to many doctors about a breast situation. She has a split nipple on one breast that inverts only when she exercises and it has discharge come out only when exercising. It is a white discharge. She has had ultrasounds, mammograms & tests by GYN doctors & breat oncologists and they said it's nothing and they don't find anything. She called me hysterical tonight because after alot of exercising tonight she now has a split in the middle of the other breast...no discharge...just a split nipple. She has large breasts and wears 2 sports bras when exercising for support. She may run on the treadmill hard for an hour and then bike. She is not anorexic or anything like that...she ran cross country about 6 years ago and has always enjoyed alot of exercise. Please tell me if other women runners or women who exercise ALOT have complained of theis nipple situation. We are at our wits end and she's worried.
