I have one VERY sore nipple! Since its just one its not thrush, right? It seems unlikely to be a latch issue because its just the left. Previously the breast (not nipple) was tender as it was healing from an incision and drainage, but the nipple has been getting more and more sore over the past few days. When LO latches it is terrible pain. After a few minutes it dulls a degree, but still hurts. After nursing the nipple is shaped like an eraser top, not flat or lipstick like. Last night I tried heating and now I have a spot that looks like a blood blister. I'm not sure if it was a blend or not and not sure what would be best to reduce the pain now. Any suggestions?
