What’s Causing My Knee Pain?
Being active is one of the best things you can do for your joints and the rest of your body. But injuries can happen, and they often involve the knees. Some of the most common problems are sprained ligaments, meniscus tears, tendinitis, and runner's knee. If you have an old knee injury that wasn’t properly treated, it may flare up now and then or hurt all the time. Several other things can also cause knee pain, such as: Bursitis: A bursa is a sac that holds a small amount of fluid that’s under the skin above your joint. It helps prevent friction when the joint moves. Overuse falls, or repeated bending and kneeling can irritate the bursa on top of your kneecap. That leads to pain and swelling. Doctors call this prepatellar bursitis. You may also hear it called ''preacher's knee."
