for 1-2 weeks.

Pain Relief
You may have pain after surgery. Your doctor may order pain pills for you. The pain medicine
may be Tylenol , ibuprofen or a narcotic.

Prevent Constipation

▪ At least 4 servings of fruits or vegetables.
▪ At least 2-4 servings of whole grain bread or cereal.

You may use a stool softener (docusate sodium) and/or a bulk fiber laxative (such as Metamucil ) to
prevent constipation. You can buy these over the counter and follow the package directions.

When to Call the Doctor
▪ Problems having a bowel movement
▪ Temperature by mouth over 100.4 θF for two readings taken four hours apart
