Often, knee pain is caused by the tendons, ligaments and muscles that surround the knee becoming too tense. Stretching before bed helps loosen the tissues that surround the knee and can reduce knee pain. Place a small pillow between your knees once you are ready to go to sleep. Your knees sometimes rub against each other when you sleep on your side, which might cause pain and discomfort. Placing a pillow between your knees helps prevent this from happening. Do light exercise during the day. When the muscles that support your knees weaken, knee pain is likely to occur.
Patellofemoral pain is a common knee problem. If you have this condition, you feel pain under and around your kneecap. The pain can get worse when you're active or when you sit for a long time. You can have the pain in one or both knees. The exact cause of patellofemoral pain isn't known. It probably has to do with the way your kneecap (patella) moves on the groove of your thigh bone (femur). Usually, putting ice on your knee, changing your activities, and following a physical therapy program works best.
