  5. It is important to eat some food every time you take narcotic pain medications (even in the middle of the night).  If you don’t, you are more likely to have nausea.  Usually a few crackers, some pudding, applesauce or a banana will suffice.

To help maintain circulation and muscle tone in your leg move your ankle and toes up and down every 30 minutes you are awake until you are more active.


  1. Once you are released from the surgery center start taking the pain medication on a regular schedule.  When your pain is well controlled, take the pain medication as needed.
  2. It is best to take the pain medication at the earliest sign of pain instead of waiting for it to worsen.  The medication works best if you ice and elevate.
