The need for pain medication varies a lot from person to person, but usually after a few doses of a strong agent like Percocet, it will be possible to control discomfort with Tylenol or equivalent. Avoid driving a car if there is any abdominal soreness that may prevent you from reacting quickly in an emergency, or if you are still taking strong painkillers. You will return home with adhesive tape on your wounds. It is quite safe to shower with the adhesive tape. Leave it be till you are seen in the office again.
Dissolving stitches are usually used, so there is nothing to remove except the tape.
It is normal for a painless, firm bump to develop under each scar. These bumps just indicate sound healing and disappear in about two months. You are encouraged to return to normal activities as soon as possible. It is vital that you get as much reasonable exercise as you can tolerate in the early postoperative period to stimulate the circulation and breathing. It is very difficult to disrupt any of the surgery, so do not be afraid that you will do yourself harm.
