RA usually presents with joint symptoms
RA may also cause:
Inflammation may also occur in
You will be asked about your symptoms and medical history. A physical exam will be done. RA is sometimes difficult to diagnose because there are several diseases with similar symptoms. Part of diagnosing RA is to rule out other diseases.
The American College of Rheumatology and the European League Against Rheumatism have created a system for diagnosing RA. To start, symptoms need to be present for 6 weeks or more. The system then uses a 10-point scale assessing specific symptoms. The higher the score, the more likely RA is present. Considered factors include:
There is no cure for RA. The goals of treatment are to:
There are a variety of medications to treat the pain and inflammation of RA. In some cases, medications may be used in combination. These may include:
Rest reduces active joint inflammation and pain and fights fatigue. Exercise is important for maintaining muscle strength and flexibility. It also preserves joint mobility.
These steps may help relieve stiffness, weakness, and reduce inflammation:
Splints applied to painful joints may reduce pain. Devices that help with daily activities can also reduce stress on joints. Devices include:
Stress reduction can ease the difficulties of living with a chronic, painful disease. Participating in an exercise program or joining a support group are 2 strategies you can use to reduce stress. Cognitive behavioral therapy, a form of talk therapy, and meditation may also offer benefits in reducing your pain and improving your ability to cope with RA.
Joint replacement and tendon reconstruction help relieve severe joint damage.
There are no current guidelines to prevent RA.
