How can you care for yourself when you have knee pain or injury?

  • Be safe with medicines. Read and follow all instructions on the label.
    • If the doctor gave you a prescription medicine for pain, take it as prescribed.
    • If you are not taking a prescription pain medicine, ask your doctor if you can take an over-the-counter medicine.
  • Rest and protect your knee. Take a break from any activity that may cause pain.
  • Put ice or a cold pack on your knee for 10 to 20 minutes at a time. Put a thin cloth between the ice and your skin.
  • Prop up a sore knee on a pillow when you ice it or anytime you sit or lie down for the next 3 days. Try to keep it above the level of your heart. This will help reduce swelling.
  • If your knee is not swollen, you can put moist heat, a heating pad, or a warm cloth on your knee.
  • If your doctor recommends an elastic bandage, sleeve, or other type of support for your knee, wear it as directed.
  • Follow your doctor's instructions about how much weight you can put on your leg. Use a cane, crutches, or a walker as instructed.
  • Follow your doctor's instructions about activity during your healing process. If you can do mild exercise, slowly increase your activity.
  • Stay at a healthy weight. Extra weight can strain the joints, especially the knees and hips, and make the pain worse. Losing a few pounds may help.

    • Increased pain, swelling, warmth, or redness.
    • Red streaks leading from the knee.
    • Pus draining from a place on your knee.
    • A fever.
  • You have signs of a blood clot in your leg (called a deep vein thrombosis), such as:
    • Pain in your calf, back of the knee, thigh, or groin.
    • Redness and swelling in your leg or groin.

Watch closely for changes in your health, and be sure to contact your doctor if:
