Last week i noticed my left nipple was kinda tender, didnt think twice, thought maybe i hit it or nicked it shaving. Well its still sore and i can feel a bump under it. Im currently on a slight cutting diet. Can this possibly be gyno, if so how much nolva should i take? I really don't want to mess w letro again, that screwed me up at the end of my cycle. I used it for a few weeks at the end to get rid of tender nips but now its just my left.
