What should you know about early ankylosing spondylitis?

Ankylosing spondylitis is an inflammatory condition affecting the spine and nearby joints. Early symptoms may include lower-back or buttock pain, morning joint stiffness, pain that interrupts sleep, and stiffness after resting that eases with movement. Some people also notice reduced range of motion in the spine, hips, or chest. These features can overlap with other causes of back pain, so symptoms alone cannot confirm the diagnosis.

A clinician may review your symptom pattern, examine spinal movement, and decide whether blood tests or imaging are useful. The condition can vary over time; a quieter period does not prove that the underlying inflammation has ended.

Book an appointment if back or buttock stiffness persists, returns repeatedly, or limits sleep and daily activity. Keep a brief record of when symptoms start, what movement does, and whether other joints or the eyes are affected. A physiotherapist can teach posture, spinal mobility, breathing, and strengthening work. Exercise therapy should be paced to your symptoms; hydrotherapy may feel easier when land exercise is uncomfortable. Medicines, including anti-inflammatory medication, should be selected with a clinician because other health conditions and medicines matter.

Seek urgent care for new loss of bladder or bowel control, numbness around the groin, or rapidly worsening leg weakness. Get prompt advice for a painful red eye with light sensitivity, fever with severe back pain, or sudden major loss of movement.

Ask whether your pattern fits ankylosing spondylitis or another cause, which tests are appropriate, and how to exercise during a flare. Ask when to involve rheumatology and how treatment will be reviewed.
