Many people start to feel pain and stiffness in their bodies over time. Sometimes their hands or knees or hips get sore and are hard to move. These symptoms may be caused by arthritis.

Arthritis is an illness that can cause pain and swelling in the joints. Over time, the joint can become severely damaged. Joints are places where two bones meet, such as the elbow or knee. Some kinds of arthritis may cause problems in other organs, such as the eyes, or in the lungs. It may also affect the skin.

There are several kinds of arthritis. The two most common ones are osteoarthritis and rheumatoid arthritis. Osteoarthritis is the most common form of arthritis. This is the form that usually comes with age and most often affects the fingers, knees, and hips. Sometimes osteoarthritis follows an injury to a joint.
