Where does ankylosing spondylitis hurt first?

Ankylosing spondylitis begins with lumbosacral pain. First, lumbosacral pain is the most common first pain in ankylosing spondylitis. This is because the sacroiliac joint is one of the earliest joints affected by ankylosing spondylitis. Patients often feel deep pain in the lower back or buttocks, which may increase after rest and decrease after exercise. It may be intermittent at first, but as the disease progresses, it becomes persistent. Second, the lumbosacral pain may gradually spread upward. As the disease progresses, the pain may spread upward along the spine, involving the thoracic and cervical vertebrae, causing stiffness and pain throughout the spine. At the same time, the range of motion of the spine is gradually limited, bending, turning and other movements become difficult. In addition, in addition to the spine and sacroiliac joints, ankylosing spondylitis may also affect peripheral joints, such as hips, knees, ankles, etc., resulting in pain, swelling and limited movement of these joints. Peripheral joint symptoms may be masked by lumbosacral pain in the early stages of the disease, but peripheral joint problems may gradually become apparent as the disease progresses. Finally, it is important to emphasize the early diagnosis and treatment of ankylosing spondylitis. If there is persistent pain in lumbosacral and other parts, especially accompanied by morning stiffness, limited activity and other symptoms, timely medical treatment should be carried out, relevant examinations, such as sacroiliac joint imaging examination, hematology examination, etc., so as to make early diagnosis, and take active and effective treatment measures to delay the progression of the disease and improve the quality of life of the patient.
