Rheumatoid arthritis (RA) affects many joints in the body. Symptoms vary from mild to severe. They may also start quickly or slowly. There may be times when symptoms are worse. These are called flare-ups. There may also be times when there are no symptoms.
Key signs of RA are:
- Pain and stiffness that is worse in the morning and after inactivity
- Red, swollen, tender, warm joints
- Joints that do not look as they should
RA may also cause problems in other parts of the body, such as the skin, eyes, lungs, and heart.
