Patient Education
Arthritis
If you feel pain and stiffness in your body or have trouble moving around, you might have arthritis. Most kinds of arthritis cause pain and swelling in your joints. Joints are places where two bones meet, such as your elbow or knee. Over time, a swollen joint can become severely damaged. Some kinds of arthritis can also cause problems in your organs, such as your eyes or skin.
Types of arthritis include:
- Osteoarthritis is the most common type of arthritis. It's often related to aging or to an injury.
- Autoimmune arthritis happens when your body's immune system attacks healthy cells in your body by mistake. Rheumatoid arthritis is the most common form of this kind of arthritis.
- Juvenile arthritis is a type of arthritis that happens in children.
- Infectious arthritis is an infection that has spread from another part of the body to the joint.
- Psoriatic arthritis affects people with psoriasis.
- Gout is a painful type of arthritis that happens when too much uric acid builds up in the body. It often starts in the big toe.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
