About an hour ago I noticed a lump high up in my breast, just below the armpit. It was quite tender to the touch (ie. when DD leant on it - ouch!) I latched her onto that side and she fed for 10 minutes or so. I can't feel a lump anymore but that side of my breast is still tender. There's no red patch. It must have appeared within the hour before I found it as I hadn't noticed it before. Can anyone shed any light? Thanks
