The ENT doctor did you no favors by putting you on the steroidal medicines for nose bleed! I am dismayed by this. That is no doubt what led to gynecomastia. Having the gynecomastia reduced by surgery should not be harmful to you. It could return if you continue to take the steroidal medicines. I would certainly consult with a different ENT doctor about the nose bleeds. Speaking from personal experience, I myself overcame a ten year battle with chronic sinus infections and nosebleeds by visiting a chiropractor instead.
surgery is not harmful. you will not get the same problem if surgery is done on the breast tissue. regarding homeopathy it is doubtful that there is a medicine in the homeopathy. if they were to be medicine than why it is not widely acceptable in the community. why is it not popular
