DEAR DOCTOR K: I have ankylosing spondylitis. Can you discuss this condition and the best way to treat it?
DEAR READER: Ankylosing spondylitis is a form of arthritis in which the spine and other joints become inflamed and stiff. A person with this condition usually feels pain or stiffness in the lower back, especially in the morning or after inactivity. Pain tends to begin in the two joints between the spine and the pelvis (the sacroiliac joints) and be felt in the buttocks. It then works its way up the lower spine.
