There will often be a little swelling around the incision site for a few weeks after the operation. A small amount of swelling is part of the normal healing process. The natural reaction to surgery is to form scar tissue that will become firmer in the first few weeks and then will slowly soften up. This swelling is typically only 1 to 2 finger breadths in size and should not get significantly bigger. If the swelling continues to get bigger, especially if it is growing quickly over a couple of hours, contact your surgeon immediately. Over the next few months, the swelling and scar tissue will disappear and the area should look and feel just like the normal skin.
