ARTHRITIS
DIAGNOSIS |
|
|
A physical examination may show that
fluid is collecting around the joint. (This is called an "effusion.")
The joint may be tender (when it is gently pressed), and may exhibit
warmth and redness, more typically in infectious arthritis and
autoimmune arthritis. It may be painful or difficult to rotate the
joints in some directions. (This is known as "limited range-of-motion.")
In certain autoimmune forms of arthritis, the joints may become
deformed, if the disease is not treated. Such joint deformities are
the hallmarks of severe, untreated rheumatoid arthritis.
Tests vary depending on the suspected cause. They may include blood
or urine tests, as well as joint X-rays. In septic arthritis, joint
fluid is removed from the joint with a needle and examined for the
presence of infection. See the specific types of arthritis. |
