What is axSpA?
Axial Spondyloarthritis (also known as axSpA or axial SpA) is one of a group of inflammatory rheumatic diseases known as Spondyloarthritis that share clinical and genetic features.
AxSpA is a progressive chronic inflammatory disease that primarily affects the spine and the sacroiliac (SI) joints that connect the lower spine to the pelvis. This results in pain and stiffness in the lower back, hips and buttocks. It can also affect other joints in the body, as well as tendons and ligaments. It causes inflammation and can lead to chronic pain, and impairments in mobility.
