Arthritis Pain
What Is Arthritis?Many people start to feel pain and stiffness in their bodies over time. Sometimes their hands or knees or shoulders get sore and are hard to move and may become swollen. These people may have arthritis (ar-THRY-tis). Arthritis may be caused by inflammation (in-fl ah-MAY-shun), of the tissue lining the joints. Some signs of inflammation include redness, heat, pain, and swelling. These problems are telling you that something is wrong. Joints are places where two bones meet, such as your elbow or knee. Over time, in some types of arthritis but not in all, the joints involved can become severely damaged. There are different types of arthritis. In some diseases in which arthritis occurs, other organs, such as your eyes, your chest, or your skin can also be affected. Some people may worry that arthritis means they won't be able to work or take care of their children and their family. Others think that you just have to accept things like arthritis. It's true that arthritis can be painful. But there are things you can do to feel better. This booklet tells you some facts about arthritis and gives you some ideas about what to do, so you can keep doing many of the things you enjoy. What Are the Types of Arthritis?There are several types of arthritis. The two most common ones are osteoarthritis (AH-stee-oh-ar-THRY-tis) and rheumatoid (ROO-mah-toyd) arthritis. Osteoarthritis is the most common form of arthritis. This condition usually comes with age and most often affects the fingers, knees, and hips. Sometimes osteoarthritis follows an injury to a joint. For example, a young person might hurt his knee badly playing soccer. Or someone might fall or be injured in a car accident. Then, years after the individual's knee has apparently healed, he might get arthritis in his knee joint. A sports injury to a knee when a person is young can lead to arthritis years later. Rheumatoid arthritis happens when the body's own defense system doesn't work properly. It affects joints and bones (often of the hands and feet), and may also affect internal organs and systems. You may feel sick or tired, and you may have a fever. Another common type of arthritis, gout, is caused by crystals that build up in the joints. It usually affects the big toe, but many other joints may be affected. Arthritis is seen with many other conditions. These include:

Joint Pain
Joint Pain The structure of a joint ![]() Joints, particularly hinge joints like the elbow and the knee, are complex structures made up of bone, muscles, synovium and cartilage and ligaments, designed to bear weight and move the body through space. The knee consists of the femur (thigh bone) above, and the tibia (shin bone) and fibula below. The patella, or kneecap rides on top of the lower portion of the femur and the top portion of the tibia. The muscles and ligaments connect these bones and the space between them is cushioned by fluid-filled capsules (synovia) and cartilage. When muscles are exercised, they pull on the bones, strengthening them. The range of motion of a joint represents how far it can be flexed (bent) and extended (stretched). Joint pain can be caused by many types of injuries or conditions. No matter what causes it, joint pain can be very bothersome. Rheumatoid arthritis is an autoimmune disorder that causes stiffness and pain in the joints. Osteoarthritis involves growth of bone spurs and degeneration of cartilage at a joint. It is very common in adults older than 45 and can cause joint pain. Joint pain may also be caused by bursitis (inflammation of the bursae). The bursae are fluid-filled sacs that cushion and pad bony prominences, allowing muscles and tendons to move freely over the bone. Causes
