Guide to Arthritis Pain

Chronic Pain

Chronic pain is a major health problem in the United States and is one of the most weakening effects of arthritis. More than 40 million Americans are affected by some form of arthritis, and many have chronic pain that limits daily activity.

Osteoarthritis

Osteoarthritis is by far the most common form of arthritis, especially among older people, affecting over 20 million Americans. Osteoarthritis is also called degenerative joint disease or osteoarthrosis.

Osteoarthritis is a joint disease that mostly affects the cartilage. Cartilage is the slippery tissue that covers the ends of bones in a joint. Healthy cartilage allows bones to glide over one another. It also absorbs energy from the shock of physical movement.

Rheumatoid Arthritis

Rheumatoid arthritis, affecting over 2 million Americans, about 75% women, is the most disabling form of the disease.

Rheumatoid arthritis affects other parts of the body besides the joints. It begins at a younger age than osteoarthritis, causes swelling and redness in joints, and may make people feel sick, tired, and (uncommonly) feverish.
