Been doing pretty good lately but today I woke up and my left nipple is sore. It feels harder than the other one. I was just in for my yearly visit with my OB last month. I've never had this happen. Only time they ever hurt was when I was breast feeding 6 years ago. It's kind of a burning stinging pain and it's constant. Trying not to let my mind go to dark places but it's hard :/ there is a bump where it hurts. Uh please help!
