While in the shower, I noticed a small bump on the top of my areola and it looked like a thick white a almost pimple like bump. I squeezed it and a thick lump of discharge came out. I cleaned it and put on a cream. It had a scan the next day and for about four more days. The scab came off in the shower and there was more discharge and now it is tender with another scab. It's now been 6 days. What is this?
