Pumpkin,
I am also one of those (gross to say) very wet girls almost like I have peed myself some times in the month and lately I have completely dried up. I don't have yeast problems but have pretty frequent BV problems. I have looked online and purchased evrning primrose oil (it's a capsule not oil) and it has seems to even me out a bit. Lately I have been itchy and very irritated (all kids of issues girl) went to the doc and guess what another bv infection but the weird thing is I don't get the nasty odor or funk, the doc didn't even know at first. Anyway I feel ya girl I am 28 and my body is getting all jacked up now but the doctors don't know why so I am glad I found this site.
There is a rare form of Breast Cancer that starts on the outside of the nipples. It is called Pagets Disease. Look it up on the internet. I have a link below that you can copy and paste. Let me know if the link works and I can try it again.
I would go and see a doctor!

Perhaps a problem with a milk duct or oil gland. Given your symptoms with the redness and pain, I would "guess" that you have an infection somewhere and need to be see by a pro. Are you having your annual mammogram's? Make sure to let the Doc know when the last on was. Please don't just take the "wait and see" approach on this. I really think you need to be seen by a doc.
Good Luck--J
