Ankylosing Spondylitis (Axial Spondyloarthritis)
What it is
Ankylosing spondylitis is a type of arthritis that mainly affects the spine. It causes back pain and stiffness, often worse in the morning. It often starts in young adults.
Common symptoms
- Low back or buttock pain that lasts more than 3 months
- Morning stiffness that improves with exercise
- Pain that wakes you in the second half of the night
- Heel pain or tendon pain (enthesitis)
- Eye inflammation (uveitis): red, painful eye; seek prompt care
What to expect at GSMC
- First visit: A rheumatologist reviews your symptoms, history and medicines, and examines your joints and skin.
- Tests: Blood tests and imaging, as needed, help confirm the diagnosis.
- Follow-up: Regular visits and lab checks help us adjust treatment over time.
Self-care tips
- Do daily stretching and posture exercises. Movement often eases stiffness.
- Take your medicines exactly as prescribed. Do not stop them on your own.
- Keep all lab and follow-up visits.
- Stay active with gentle exercise, and rest during flares.
When to call us
- A red, painful eye or blurred vision: get care the same day
