What should you know about Zach from the Try Guys and ankylosing spondylitis?

Ankylosing spondylitis, also called axial spondyloarthritis, can cause inflammatory pain and stiffness around the spine and pelvis. Morning joint stiffness, reduced range of motion, and discomfort that changes with activity may occur. Symptoms vary, and back pain alone does not establish this diagnosis. Assessment may include a physical examination and tests chosen for your pattern of symptoms.

Write down the location and timing of stiffness, changes in movement, sleep disruption, and any eye, skin, or bowel symptoms. Arrange a review if symptoms persist or restrict work, exercise, or sleep. Care may include [Ankylosing Spondylitis](/conditions/ankylosing-spondylitis/), [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/), [Exercise Therapy](/treatments/physiotherapy-and-rehabilitation/exercise-therapy/), or medication selected with a clinician.

Seek urgent help for sudden loss of bladder or bowel control, new leg weakness, numbness around the saddle area, severe injury-related back pain, or a painful red eye with vision changes. These signs need prompt evaluation and should not be attributed to a celebrity’s diagnosis.

Ask whether your symptom pattern suggests inflammatory back pain, whether imaging or blood tests would help, and which movement plan is safe. Ask how to monitor stiffness and what changes should lead to an earlier appointment.
