if it hurts and there's a bump, it's the beginning of gyno IF he has been using..Has he been on the sauce recently? I would suggest a regime of letro/nolva depending on what he used to get the gyno, 2.5 letro (or 1.5 starting out) and 40mgs a day until the gyno is gone. This guy should wait until he resolves his gyno problem FIRST or it will get worse and trust me, I just had gyno surgery and it's not fun when you screw up..
