This is a question best answered by your surgeon. It's really going to depend on what type of surgery you are having and whether or not your job is strenuous. In general, I like my patients to take off a couple of days to a week before returning to work. Best of luck.
Your Gynecomastia condition can be treated and you can walk a day later and to go back to a desk job after 3 days.We have patients that do it friday and go back to work Monday. For evaluation and best results you need a surgeon who specializes in gynecomastia surgery.
