Rest and protect an injured or sore area. When resting, place a small pillow under your knee. Ice will reduce pain and swelling. Apply ice or cold pack for 10 to 20 minutes,3 or more times a day. Compression, or wrapping the injured or sore area with an elastic bandage will help decrease swelling. Elevate the injured or sore area on pillows while applying ice and anytime you are sitting or lying down. There are many vitamins and natural supplements you can take to help rebuild cartilage and increase blood flow. wishing you good health. Regards. Dr. Saurabh gupta </s>
