Natural treatments or cures for knee pain include following the RICE protocol; treating arthritis pain with supplements, tai chi or exercise; and heat and cold therapy. Appropriate treatments depend in part on the cause of the knee pain, explains Healthline.
The RICE protocol, which calls for rest, ice, compression and elevation, is typically used for knee pain due to sprains and strains. Knee pain and swelling from other causes can also be treated with cold compresses or heating pads, which reduce stiffness, according to Healthline. Some people find supplements such as willow bark, ginger, glucosamine and chondroitin sulfate beneficial. Exercise such as tai chi or other exercises that put the knee through a full range of motion are also useful, especially for people with arthritis.
