I do think it caused problems with my right breast. That was the breast that got infected 3 years ago, when I took them out. The flow on that side is really slow, and comes out in 4 streams at most, usually just 3, when I pump. My left breast is the one bothering me today, and that one completely healed, and I have no problems with the flow of milk. That one's actually my super producer. I leak from the piercing holes ALL the time.
The red area is below my nipple, kind of on the bottom of my left breast. I don't think it got clogged, but I was a little engorged this morning. After I nursed the LO, it solved that problem (he's such a piggy boy). I think I'm just in the very early stages of it. I nursed him on that breast, and it wasn't too bad. Stung/burned a little bit, but that was it.
