Breastfeeding my 9 mo and over the last month or so I've been getting lumps in my left breast, not full mastitis just a blockage. But it's really painful, takes a few days to go and then is back again. I've also noticed now it's moving around my breast, from the top to the outer side, now it's underneath. I do all the putting heat on and massaging during feeds, dangle feeding etc. I had thought it was my bra, started wearing a smaller one as DS has dropped a couple of feeds, I didn't feel as big but I've gone back to my bigger bra in case it was pushing into me. I don't want to stop BF but I'm worried there's something wrong here. I suspect lazy latch or something to do with DS's top teeth coming through that he's changing feeding positions. Anyone else experienced this and should I see a doc?
