What are ankylosing spondylitis symptoms?
Fatigue is a common symptom associated with active inflammation. Inflammation of the spine causes pain and stiffness in the low back, and upper buttock area. The onset of pain and stiffness is usually gradual and progressively worsens over months. The symptoms of pain and stiffness are often worse in the morning or after prolonged periods of inactivity. The pain is often eased by movement, heat, and a warm shower in the morning.
Chronic spondylitis and ankylosis cause forward curvature of the upper torso. Spondylitis can affect the areas where ribs attach to the upper spine, further limiting lung capacity. AS can cause inflammation and scarring of the lungs, causing shortness of breath, especially with exercise and infections.
