Waking up with back pain every morning may be due to physiological factors such as not paying attention to the sleeping posture at night or often sleeping on a hard bed; it may also be due to pathological factors such as dorsal myofasciitis and ankylosing spondylitis. 1. Physiological factors: If you don’t pay attention to your posture at night, or sleep on a hard bed, so that your muscles are continuously squeezed, it may cause pain. 2. Dorsal myofasciitis: Also known as myofascial pain syndrome, it is mainly characterized by pain and is usually associated with trauma, strain and other factors. Repeated stimulation will take the fascia as the trigger point, thus causing muscle pain, and the symptoms are more obvious when waking up in the morning. 3. Ankylosing spondylitis: mainly involves the spine or sacroiliac joints, manifested as lower back pain, and accompanied by a feeling of stiffness, repeated compression of the local area at night when sleeping, affecting blood circulation, the pain will be significantly worse. Getting up every morning with back pain may also be a lack of calcium or lumbar muscle strain, lumbar intervertebral disc herniation caused by radiating pain. It is recommended to go to the hospital in time and standardize the treatment under the guidance of the doctor.
