I am only 16 years old and is scared to death right now. You see im anemic, just though i would throw that in there because it could be a cause. But i found this lump, i think it may have been one, under my nipple on my left breast. Now for a while it was really sore to the touch that i couldnt even sleep on my stomach. So the pain went away, but now everytimes you squeeze my nipple, i have this brownish really watery fluid come out of the side of my nipple. I have back pain, constant urinatioin, i feel dizzy and nauseated...doc can you please tell me what could be wrong with me...im an athlete and i need to know whats wrong before i hit the court...please don't tell me its breast cancer!!!
