Ok so Lo was feeding from my left yesterday all was fine then suddenly got a bad pain round the nipple area, it felt like Lo bit me which he often does, afterwards it was very tender and felt bruised. Next time I fed on it the pain was really sharp, it felt like when u feed in the early day when they are cracked & sore. Through the day I noticed the entire boob getting more and more tender especially underneath where your bra goes and round the side near my arm pit. i forced Lo to feed from it before bed and by the end of the feed the nipple still hurt but not as bad but the boob is still so sore. I expressed for over an hour after Lo was in bed but although I got a normal amount of milk out and they felt empty I couldn't feel any lumps but they were still tender, this morning I feel so full and the tenderness is bad it hurts to put my arm by my side. The nipple still hurts a bit but not as bad. Any ideas what could be wrong or what I should do????
