Gyno: Alternative solutions to surgery?

I have had a moderate case of gynecomastia since I was 10 years old. Although the pain is mostly gone now, it really hurt tremendously in the early stages (the first year). Itchiness has persisted over the years and the hard lump under my left nipple is a little bigger than the lump under my right. I am going to get surgery soon but I understand that surgery is a long painstaking process. Although I am willing to go under the knife, I’d like to know if there are any alternative solutions to getting rid of my problem.
