Ankylosing Spondylitis

Ankylosing Spondylitis

Ankylosing spondylitis is swelling and soreness of the joints in the spine and pelvis. It is an autoimmune disease. This means the body attacks its own healthy tissues. As the body tries to heal itself, new bone is formed. Over time, the bones in the spine can fuse or join together. This problem often causes pain and stiffness in the lower back area. You may also have problems with your upper back, neck, chest, hips, or shoulders. Sometimes, this problem can affect other areas like the eye or heart valves. It may also cause problems with stiffness in the ribs. This can make it hard to breathe when doing exercise.
