Frequently asked questions
Why does exercise help ankylosing spondylitis?
Movement keeps the spine flexible and reduces stiffness, unlike ordinary back pain. Regular exercise is one of the most important parts of treatment.
Can ankylosing spondylitis affect the eyes?
Yes. It can cause a painful, red eye (uveitis). Sudden eye pain or blurred vision needs prompt medical review.
