Its actually under the bit that is around the nipple, the darker colour skin bit (I always forget what its called). I noticed it about a week ago as it felt slightly tender. Now it doesnt hurt at all.
How long would it usually take for a spot/small cyst or something like that to go away? A couple of weeks? Or is it more likely to be something to do with milk glands etc seeing as its near the nipple? I have a 5 month old baby, stopped BFing 4 months ago.
