I naturally had gyno with out the use of any steroids. I never thought too much about it till just now. I'm not sure how gyno is started and all, but If I had it naturally, does this mean I possible have high estrogen or low testosterone? Im 18, should I go get some blood work done? I however did get it surgically removed last year. There is still a little lump underneath the nipple, it is not soft though it is kind of hard. What can this be?
