How to Treat Knee Pain After Running
Runner’s knee and other minor injuries that occur from running can often be treated at home. Your treatment will depend on the severity of your symptoms.3 Your healthcare provider can recommend treatment options for you. One of the most common at-home treatment for runner’s knee uses the RICE method to ease symptoms:3
- Rest. Avoid putting any weight on the knee.
- Ice. Apply cold packs wrapped in a towel for no more than 20 minutes at a time, several times each day. Avoid applying ice directly to your knee.
- Compression. Lightly wrap your knee using an elastic bandage. Leave an opening over your kneecap. Make sure the bandage is not wrapped too tight and does not cause pain.
- Elevation. Rest with your knee elevated higher than your heart.
In addition to the RICE method, over-the-counter pain medications may relieve your pain. Non-steroidal anti-inflammatory drugs like Advil are good options for easing pain associated with runner’s knee.3 Your healthcare provider may also recommend special shoe inserts that can stabilize and align your foot and ankle, taking stress off your lower leg and knee.3
