I have a pretty big birth mark on my boob. My birth marks are all naturally raised bumps, and not flat. So they're filled with tissue or pus I assume.

The one on my boob has been sort of bothering me lately, like tingling, sort of hurting? The look of it hasn't changed. But I think it has something to do with my boobs getting bigger and preparing for milk. I've had colostrum for months now.
