Lower-back pain and morning stiffness push many IBD patients to search ankylosing spondylitis IBD or Crohn's spine pain. Axial spondyloarthritis, including ankylosing spondylitis (AS), can overlap with Crohn's and ulcerative colitis. Peripheral joint pain is common too; this article focuses on the spine and sacroiliac pattern.

Patterns worth reporting

• Deep buttock or low-back pain that eases with movement and worsens with rest
• Morning stiffness lasting longer than 30 minutes
• Night pain that wakes you for reasons other than bathroom trips
• Heel, chest-wall, or Achilles tendon pain alongside IBD

Not every backache is inflammatory. Mechanical strain, deconditioning, and steroid-related bone changes still matter. Start with IBD joint pain and arthritis and leg and knee pain.

Care team coordination

Rheumatology often co-manages axial disease. Some biologics used for IBD also treat spondyloarthritis; your teams decide together. NSAIDs that help AS may irritate the gut, so do not self-start high-dose ibuprofen without guidance.

Questions for clinic

• Do I need imaging or HLA-B27 discussion, or is this mechanical pain?
• Which pain medicines are safer with my IBD history?
• Could one therapy cover gut and spine inflammation?
