I'm a bit confused right now about how to handle this news.

This past week I went to the doctor about my high blood pressure and mentioned the soreness around my right nipple. After examining me, he said I have gynecomastia. I guess I'm not really surprised as I am 55 yrs old, 5'8" and 245 lbs. I'm confused because I have feelings of both "not another problem" and "WOW".
