The main symptomatic manifestations of spondyloarthritis include inflammatory low back pain, attachment point inflammation, and extra-articular symptoms. Symptoms of spondyloarthritis vary from person to person. Some patients may experience inflammatory low back pain with morning stiffness, which is relieved by activity. Some patients may also experience attachment point inflammation, swelling and pain in the peripheral joints, limitation of movement, and extra-articular symptoms, such as uveitis, anterior infection, and so on. Clinical spondyloarthritis, if the treatment is not timely, there may be complications, such as heart damage, lung damage, digestive system damage, urinary system damage, etc., which have a greater impact on the patient’s body. If spondyloarthritis is already present, it is recommended to actively seek medical treatment to avoid complications.
