I have a hard, marble shaped and sized lump on the side of my breast towards my armpit. I noticed it on Monday. I've been massaging it but it won't shift. I've been making sure DS feeds on that side but he only ever takes one side so its difficult and I don't want to let the other side get engorged.
That side is aching but its difficult to tell if that's just general feeding pain or as a result of this lump - DS is 3 weeks and has a poor latch.
