After gynaecomastia surgery you may need drains to help to prevent haematomas and seromas (blood and tissue fluid collections). Expect to wear a compression garment for a few weeks while you recover (not needed). This will reduce swelling and discomfort and help you heal faster. Do not do any vigorous exercise or activity for about 3 weeks.
There may be some numbness or loss of sensation. This is usually temporary but, depending on the technique needed, there may be some permanent loss of nipple sensation.
You should be able to return to work within a week after gynaecomastia surgery. Normal activities can resume within a month provided you ease back into your regular routine.
