Stop, change, or take a break from any activity that may be causing your pain or soreness. </p><p>When you rest, place a small pillow under your knee. </p></li> <li>Use ice. <p>Put ice or a cold pack on your knee for 10 to 20 minutes at a time. Try to do this every 1 to 2 hours for the next 3 days (when you are awake).</p></li> <li>Wrap the affected area. <p>Compression, or wrapping the area with an elastic bandage (such as an Ace wrap), will help reduce swelling.</p><ul><li> Don't wrap it too tightly, because that can cause more swelling below the affected area. Loosen the bandage if it gets too tight. Signs that the bandage is too tight include numbness, tingling, increased pain, coolness, and swelling in the area below the bandage. </li><li>Don't expect the bandage to protect or stabilize a knee injury. </li></ul></li> <li>Elevate the affected area. <p> Try to keep the area at or above the level of your heart to help reduce swelling. Prop up the area on pillows while you apply ice and anytime you sit or lie down.</p></li> <li>Try not to put weight on your knee. <p>Do this until you can get advice from your doctor.</p><ul><li>Use a cane or crutch in the hand opposite your painful knee. </li><li>Use two crutches, keeping weight off the leg with the sore knee. You can get canes or crutches from most drugstores. Crutches are recommended if a cane causes you to walk with a limp. </li></ul></li> <li>Avoid more swelling. <p>For 48 hours, avoid things that might increase swelling. These things include hot showers, hot tubs, hot packs, and drinks that contain alcohol.</p></li> <li>Apply heat. <ul><li>After 2 or 3 days, you can try applying heat to the area that hurts. Types of heat therapy include microwavable packs and disposable heating patches.</li><li>Apply heat for 10 to 20 minutes at a time.</li><li>You might also try switching between cold and heat.</li></ul></li> <li>Rub the area. <p>Gently massage or rub the area to relieve pain and encourage blood flow.
