This is SOOOOOO weird.
I have been having a similar pain in my breast for about a month or so now. I just got to really worrying about it last night, and told my fiance about it. Of course, I am thinking breast cancer, because I take my worries to the worst level, like 0 to 60. I know I need to get this checked to preserve my sanity... but in the meantine, I had just logged onto this site to post a question about my situation, more specifically how I am terrified I'm going to die and leave my son alone. UGH.
I am on bc pills, so I don't know if that's causing anything. My pain is kind of under my left breast, just a twinge of a pain, certainly nothing really bothersome, just enough to be noticeable, and it does kind of seem to twinge toward my nipple. Otherwise, I don't have any breast pain related to menstural cycles, etc., just this odd little nuisance of a pain, just enough to send me into a worrying frenzy.
Also wondering what this could be... waiting for a call back from my doctor to schedule an appt.
