Well, here goes...

Usually right before my period, my boobs get tender/sore. I noticed my left boob only got this way in certain areas, not the right. Next day it didnt go away, and when i pressed down there was a dull aching, it didnt neccessarilly hurt, but still...

When i was in the shower, i look down and notice my left nipple is hard, and looks larger than the right. It looks alittle redder, its definently swollen i think. The tissue surrounding the very tip is very hard and tough, and overal this makes it rounder and thicker than my right.

I know this isnt normal. i just noticed this. I know im not pregnant. Help Please? :/
