DC2 is 6 months old and so far beastfeeding has been successful for both of us. However in the last week or two I started to get a really sharp, stabbing, "twisting" pain inside the breast, just behind the nipple about half an hour or so after feeding. It only occurs on one side, but after every time I feed on that side (I alternate). I get short bursts of this intense pain for about 30-40 minutes, starting about half an hour after a feed, then the breast is OK until after the next feed. I never experinced this before in breastfeeding DC1 for over a year or DC2 until the last couple of weeks. Should I get it checked out? Has anyone else had a similar experience?
