Changes in the location of joint pain
The initial pain caused by ankylosing spondylitis is not always located in the lower back, however. For example, females have reported experiencing pain in the neck more frequently than males. Children almost never experience pain in the back, but rather in their heels or knees.
In addition to lower back involvement, other symptoms include:
- Joint pain. 50% of patients with ankylosing spondylitis will develop inflammation of joints in the arms and legs. Inflammation that causes knee pain, ankle pain or shoulder pain is most common.
- Eye pain. Eye inflammation (iritis) occus in 25% of ankylosing spondylitis patients. Iritis causes redness and eye pain and can be a serious condition. Iritis requires immediate attention by an ophthalmologist.
- Respiratory difficulty. The rib cage may fuse, which can limit normal expansion of the lungs and cause breathing difficulties.
- Cardiac problems. Rarely, ankylosing spondylitis can affect the heart.
- Shoulder and knee stiffness. As stiffness in the lower back limits the patient’s movement, flexibility in these smaller joints also decreases
