Call for urgent help if you had a local anesthetic and your side effects worry you or do not get better. After a general anesthetic, get help if side effects worry you or do not improve, and call if you have trouble breathing, a chest infection, a serious allergic reaction, or long-lasting confusion. Side effects like sleepiness, sore throat, shivering, nausea, or vomiting are common and usually get better within minutes or hours, but some can last longer.

You should also call if you have signs of a problem after surgery, such as pain that will not go away or gets worse, a fever over 101 F or 38.3 C, continuous vomiting, redness, swelling, bleeding, bad-smelling drainage from the wound, strong or continuous belly pain or swelling, or no bowel movement for 2 to 3 days after the operation. If you are unsure, contact the hospital or your surgical team.
