Does ankylosing spondylitis cause joint stiffness?

Joint stiffness is a common presentation of ankylosing spondylitis, often more noticeable after rest or on waking. Inflammation can affect the joints between the spine and pelvis and may involve other joints. Stiffness may ease somewhat with gentle movement but return after prolonged inactivity.

Ankylosing spondylitis is an inflammatory condition that can cause pain and stiffness in the lower back, buttocks, or hips. Symptoms may alternate sides or be accompanied by reduced spinal flexibility. The pattern, duration, and associated symptoms help a clinician distinguish inflammatory stiffness from other causes.

Some people also develop discomfort where tendons or ligaments attach to bone, such as near the heel. Joint stiffness has many possible explanations, so an assessment is needed for a reliable diagnosis.

Gentle daily movement, posture practice, and exercises that maintain spinal and hip mobility can help preserve function. A physiotherapist can tailor stretching, strengthening, and breathing exercises to your abilities and adjust them during flares.

Break up long periods of sitting with brief movement. Warmth may make morning movement more comfortable for some people. A rheumatology clinician can discuss medicines and monitoring when inflammation is affecting daily activities.

Arrange a medical review if stiffness repeatedly lasts after rest, interferes with sleep or work, or is paired with persistent back or buttock pain. Seek urgent care for new weakness, loss of bladder or bowel control, numbness around the inner thighs, or sudden severe pain after an injury.

Ask whether your stiffness pattern suggests inflammation, whether referral to rheumatology is appropriate, and which tests could help. Ask for an exercise plan that protects mobility during a flare and guidance on symptoms that require prompt contact.
