Puffy nipple after liposuction
Three weeks is still early within healing time after surgery. Swelling can last up to six weeks and may be asymmetrical. I recommend giving yourself more time to heal before evaluating results but it is best to have a follow-up examination with your surgery if you are still having concerns.
Unhappy with male breast surgery
If you are unhappy with your male breast surgery, you can consider a revision surgery; however, I would wait a good three months to allow all of the swelling to subside.
Swelling and incision lines need time to heal and mature. You are way too anxious way too early. Go for your routine checkups and ask your doctor. Incidentally you look fine for only being such a short time post surgery. My Best, Dr Commons
