Has anyone experienced this? I've been having nipple pain, so I called the LC. She asked me about obvious cracking, bleeding, etc then asked if my nipple turns white and/or other colors after nursing. Why, yes, they do! So she told me to try putting a warm washcloth on my nipples, and if it helped, to go to my doctor about it. Of course, I've been researching it, but I'd like to know if any one here has experienced this and what you did about it.
