Typically, septic arthritis affects one large joint in the body, such as the knee or hip. Less frequently, septic arthritis can affect multiple joints.

Your doctor will want to know whether you have any family
members who have ankylosing spondylitis or a related joint disease. Many people
with ankylosing spondylitis have a family member with the same condition. He or
she may also ask whether you have had ongoing diarrhea, abdominal (belly) pain,
multiple infections of the
cervix (in women) or
urethra (more common in men),
psoriasis, or inflammation of the eye chamber (uveitis). These could be clues to having a condition
other than ankylosing spondylitis.
You will have a physical exam
to see how stiff your back is and whether you can expand your chest normally.

spine and pelvis to check for bone changes (bony erosions, fusion, or
calcification of the spine and
sacroiliac joints). Certain changes in the sacroiliac
joint confirm the diagnosis of ankylosing spondylitis. But those changes can
take several years to develop enough to show on X-ray.
CT scan are more sensitive than X-ray. If no changes
to the sacroiliac joints show on the X-ray but your doctor still suspects
ankylosing spondylitis, an MRI or CT scan may allow an earlier diagnosis.
Ultrasound is being studied as a way to diagnose
ankylosing spondylitis earlier.
genetic test, which may be done
to determine the presence of a
gene (HLA-B27) that is often linked with
ankylosing spondylitis. Many people who have the HLA-B27 gene will not develop
ankylosing spondylitis, so having this test will not confirm whether you have
the condition. But the test results can be helpful if your symptoms and
physical exam have not clearly pointed to a diagnosis.
