Yeah, if you have the financial means to do so, go to a specialist. I had to try to attack gyno with clandestinely-acquired knowledge and a bunch of little dropper bottles. It got a lot better, but I still have a small lump at the bottom of one nip which has hardened.
I have to assume that a doctor could have saved my ass, but I decided to just save up for the surgery. That way, I won't have mammary glands at all and won't have to worry about it any longer. Insurance doesn't typically cover that anyway as it is considered cosmetic. From how it sounded when I did have insurance, you basically have to be diagnosed with male breast cancer to have insurance pay for that op.
