DS2 is 13 weeks and feeding is fine. I can get very full at night as he doesn't wake til 2,3 or sometimes 4am, and so I need to express a bit sometimes in the night so he can latch on. Anyway, since yesterday morning, the far side of my left breast has been sore and tender. I thought it was related to the exercise I had started, until I realized it's just on the one side. But that sort of workout pain. I just had a look now and there seem to be red veiny lines in that area, that weren't there before (they are breastfeeding veiny at the moment iykwim, but these are not red). But I can't feel any lumps. Any ideas? I really don't want to get antibiotics as I am susceptible to thrush when feeding and really don't want that at this stage. Thanks in advance!
