I started relactating a few weeks ago, but didn't get serious until a few days ago. I have been pumping like crazy, between 8 and 10 times a day. After I pump for about 20 minutes, I manually express to make sure I completely empty my breasts. Yesterday, while I was manually expressing, I felt a huge lump on my right side. It isn't really hard, but its about the size of a ping pong ball, really deep, kind of close to my nipple. I was thinking maybe it was a clogged milk duct, so in the shower tonight I tried to massage it in the hot water. I massaged my left side too and felt the same thing in the same place. I don't feel it much when I just rub it (like a self breast exam) but more when I squeeze to manually express.
Does anyone have any idea what this is? Should I be worried? If it's on both sides, what are the chances it's a clogged duct? Is it maybe just an increase in breast tissue? Has anyone expereinced anything like this? Of course it's Friday night so I can't get ahold of my doctor until after the weekend!
