I am 24, my breasts having been hurting constantly for weeks now. They usually hurt just before my periods, but they haven't stopped hurting this time. I also get stabbing pains in my chest. Like a trapped nerve. It may well be a trapped nerve that I catch occasionally, but I just wanted some advice. I'm not really in the age group for growing breasts anymore, so it worries me a little. I know it's not pregnancy because I was on the pill with my previous partner, and though I am not on the pill now, I have not had any sexual contact with anyone since we broke up and have had two regular periods since.
