Lump under nipple

Hey guys, i am in my post cycle therepy right now, and a couple of weeks ago i noticed a little lump under one of my nips that wasnt there before. I guess it's a little gyno forming, it's just a small lump? I never even had any symptoms or warning, no itchiness or tenderness, i just feel them every once in a while to check. Is there anything i can do to make it go away or am i stuck with it? It's not noticible at all, i would just rather not have it.

P.S. also i have been taking nolvadex at 40mg. ever since i discovered it, now taking a 20mg for past week.

Why did you lower your dose of Nolvadex did the lump go away?
