So by what I've read it sounds like I have a Bleb. The only confusing thing to me is it seems to have started as a sore and turned into a bleb. Is that possible?

The first days home I leaked a lot. The nursing pads I used were sticking to my nipple, only on the one side that didn't leak as much, and it caused me to develop a sore on that nipple. After stopping use of those pads and using lanolin it seemed to finally be almost healed after a couple weeks. Then, after losing my supply a little due to sickness, my supply finally came back the other day. Meaning that side became engorged as it had before. Now the spot turned from red to white (with a little red) and is even more painful than before.

So, is it a bleb? It is bigger today than yesterday as well.
