Sometimes it does go away. Your parents have good intentions but my guess is, like most other people, they have no idea what gynecomastia is. As far as your doctor, he probably doesn't know either. Again, good intentions, but no knowledge of the problem. You have no money? Call around and find a PS with no consultation fee. If they have no fee, they're probably less experienced but a hell of a lot more experienced with gyne than your family doctor is.
