I had the super-sore nipples about six months ago, now I seem to have leaky / crusty nipples (both sides). A bit of googling tells me this is probably duct ecstasia and can happen in peri. But how come nobody mentions this - is it rare, or just too icky to discuss? 
I think peri has hit me with a vengeance over the last couple of weeks. Crusty nipples, itchy foof, acne, occasional night sweats, and 5 days late for AF.
