I have a swelling right next to the nipple (on the aereola) and I think maybe it's an infected or plugged Montgomery gland. Does anyone have experience with this? It is EXCRUCIATING when he latches on that side. I'm in tears when he does and I usually have to cut him off before he is ready because it's so painful. It showed up a few days ago, only on that side. When it first showed up it almost looked like a blister and now it's a little scab.
