Treatment for knee pain depends on the specific injury. Mild to moderate injuries that cause knee pain will often heal on their own, given time. To speed the healing, you can: rest the knee for a few days and avoid intense activity, ice the knee to reduce pain and swelling, compress the knee using elastic bandage, straps or sleeves to keep down swelling, elevate the knee on a pillow when sitting or lying down and take some painkillers as prescribed by a doctor.
