My DS is almost 6 months old. Had quite a few difficult weeks of breastfeeding in the beginning but we found our groove and have had no issues for the last 2/3 months. During the feeds today I thought he had bitten my nipple a couple of times as I had a quick sharp pain. It still hurt so I had a look and I have what looks like a yellow head on my nipple. Lots of googleing and I think it’s a milk bleb. Has anyone had one of these? How did you get rid of it? Does this mean I have mastitis or potentially will get it? Is it worth going to the doctors for?
