What should you know about rheumatoid ankylosing spondylitis?

Ankylosing spondylitis, also called axial spondyloarthritis, commonly involves the spine and the joints linking the spine to the pelvis. Inflammation may cause back or buttock pain, morning joint stiffness, reduced range of motion, and fatigue. Symptoms can vary over time. Rheumatoid arthritis usually follows a different pattern, often involving the small joints of the hands and feet, so a clinician should confirm which condition explains your symptoms.

Joint stiffness or morning stiffness has many possible causes. It does not by itself identify ankylosing spondylitis.

Book an appointment with a rheumatology clinician if stiffness persists, improves with movement but returns after rest, or restricts daily activities. Assessment may include a history, examination, blood tests, and imaging. The care plan can combine anti-inflammatory medication with physiotherapy, posture work, breathing exercises, and exercise therapy tailored to your mobility.

Regular gentle movement is often easier to maintain than occasional strenuous sessions. Hydrotherapy may feel more comfortable when land-based movement is difficult. Follow medicine instructions and discuss pregnancy, other conditions, and side effects before changing treatment.

Seek urgent care for new weakness, numbness around the inner thighs, loss of bladder or bowel control, or severe pain after a fall. Seek prompt assessment for a painful red eye with light sensitivity, sudden chest symptoms, or rapidly worsening back pain. These features need evaluation rather than routine exercise advice.

Ask: Which inflammatory condition fits my pattern? Do I need imaging of the spine or pelvic joints? Which movements should I practise daily? Would physiotherapy or hydrotherapy suit me? How will we monitor medicine benefits and side effects?
