I'm starting to think I'm a litany of aches and pains....
Lately my left nipple has been itchy. Tonight I was looking at why it was itchy (as it was getting itchier) and I discovered a lump behind the nipple.
It feels like a grape...or eyeball.
It moves when I feel it.
Inside the nipple it feels fiery.
No discharge other than milk.
Could this be the start of mastitis (I've never had mastitis before which is why I'm asking) or something more sinister?
