Well it got worse before it got better! I saw the dr on Tues night and she gave me a script for ABs...it had developed a blood blister by then, and proceeded to bleed on Wed (still agony to feed). By yesterday my whole breast was really sore and I was feeling fluey too but the ABs obviously finally kicked in and today it's feeling much better, the nipple pain is significantly better too and it's visibly less red and looking better. Phew!
