After a brachioplasty, there will be some swelling and bruising which should settle in a matter of days or weeks. Hands and wrists can swell after an arm lift so when resting you should keep your arms elevated on pillows at your sides to reduce swelling. Excessive scarring, numbness, infection and delayed healing are infrequent risks. It is important to note that smoking slows down the healing process, increasing the risk of scarring and developing an infection.
