Early Signs of Ankylosing Spondylitis

Early ankylosing spondylitis often presents with persistent lower-back or buttock pain, morning stiffness, and symptoms that improve with movement rather than rest. The discomfort may develop gradually and can feel different from a simple muscle strain. Pain may wake you during the second half of the night, or alternate between the left and right buttock. Stiffness can affect the lower spine, hips, or the joints where the ribs meet the spine.

Ankylosing spondylitis is an inflammatory condition involving the spine and the joints between the spine and pelvis. It is also known as axial spondyloarthritis. Early symptoms can include reduced spinal flexibility, pain around the hips, or tenderness where tendons and ligaments attach to bone, such as the heel. Some people also develop eye redness with pain or sensitivity to light, bowel symptoms, or marked tiredness. These features do not confirm a diagnosis on their own; several back conditions can cause pain and stiffness. A clinician considers the symptom pattern, examination findings, medical history, and appropriate tests.

Arrange a medical assessment if back or buttock stiffness keeps returning, lasts for weeks, began relatively early in adulthood, or is interfering with sleep and everyday movement. Before the appointment, record when pain begins, whether activity changes it, how long morning stiffness lasts, and any episodes of eye, skin, bowel, or heel symptoms. Gentle movement is often more comfortable than prolonged bed rest, but avoid forcing a painful range. A clinician may discuss anti-inflammatory medication and refer you for physiotherapy, where posture, spinal mobility, breathing movement, and a sustainable exercise plan can be assessed.

Seek urgent medical help for new loss of bladder or bowel control, numbness around the groin, or weakness that is worsening in both legs. Prompt same-day assessment is also appropriate for a painful red eye with blurred vision or light sensitivity, because inflammatory eye problems need timely treatment. Get urgent advice after a significant injury if you have severe spinal pain, or if fever and feeling acutely unwell occur with new back pain. These warning signs need attention regardless of whether ankylosing spondylitis is suspected.

You could ask: Does my pain pattern suggest inflammation or another cause? Should I be assessed for axial spondyloarthritis? Which movements are suitable while symptoms are active? Would physiotherapy or exercise therapy help preserve spinal and hip movement? What symptoms should prompt an urgent call? Mention any family history of inflammatory arthritis, psoriasis, inflammatory bowel disease, or unexplained eye inflammation.
