i also have a very itchy left nipple. i've had it for at least half a year now and i moisturize everyday but it's making no difference. it's gotten so bad that during the night when i'm sleeping, i scratch it and i wake up and it's usually bleeding. i've taken the top layer of skin off and everything... D: i really don't know what to do.
Just use some fragrance and color free lotion, like aveeno or Vaseline intensive care lotion.
I had that same problem, but mine was from dry skin. I just used regular lotion and it stopped.
That's the thing. I don't know what to use to make it stop itcing. A cream might make it worse. I thought of neosporin cream.
Are you keeping moisturized?
