I'm turning 20 in a few months and I noticed 3 weeks ago that I have a lump in my right nipple. My nipple never got itchy, puffy, sensitive, or sore. I never had this when I went through puberty, I never ran any prohormones or any steroids. My body fat is 11% so I have no idea how this spontaneously arises.
I went to the doctor today, they did some tests, results should be in tomorrow but they said it's not a tumor.
Worst case, if it turns out to be gyno, should I run letrozole for a few weeks and then nolvadex to prevent an estrogen rebound to try to get rid of it? I know my sex drive will be shot but i'm not sure what else to do.
Also, for someone with pre-disposed gyno, is aromasin a better choice on cycle than arimidex? (Just wondering, wanted to cycle in a year or two but now I don't know if that's going to happen)
