The symptoms of low back pain may be caused by factors such as fasciitis, ankylosing spondylitis, and strain on the muscles of the low back. 1. Fasciitis: due to cold stimulation or excessive exercise, it can lead to aseptic inflammation of the fascia of the lower back, causing edema, exudation and fibrous degeneration changes in the tissues, thus causing soreness, numbness, pain and other symptoms in the lower back. 2. Ankylosing spondylitis: the body’s immune system attacks the joints, leading to changes in the joints, spine and other structures, resulting in stiffness, pain and limitation of the joints and other parts of the low back. 3. Lumbar back muscle strain: sedentary or lumbar back muscle fatigue can lead to chronic strain on the muscles, ligaments and other soft tissues of the lumbar back, which can cause a localized inflammatory reaction in the lumbar back, affecting the blood circulation of the muscles and making the symptoms of lumbar back pain appear. When the symptoms of low back pain appear every day, it is recommended to go to the orthopedic department of the hospital in a timely manner, in order to carry out a comprehensive examination to identify the cause of the disease.
