Back pain, the diseases that need to be alerted are muscle injury, fasciitis, ankylosing spondylitis, cervical spondylosis and so on. 1. Muscle injury: back pain may be caused by overwork, cold, trauma, chronic strain and other reasons, resulting in back muscle injury, which may manifest as back pain and other symptoms. 2. Fasciitis: Fasciitis of the back caused by prolonged head-down, desk work, bending and other activities may cause repeated pulling of the soft tissues on both sides of the back, localized congestion and edema, and the formation of aseptic inflammation, which will lead to back pain. 3. Ankylosing spondylitis: due to genetic, infectious, environmental and other reasons, patients with ankylosing spondylitis may experience back pain. 4. Cervical spondylosis: Degenerative lesions of the cervical spine such as intervertebral joints and ligaments are the main cause of cervical spondylosis. And these degenerative tissues will press and stimulate the adjacent blood vessels, nerves, spinal cord, etc., and back pain and stiffness will occur. Back pain may also be related to internal diseases such as lung disease, heart disease, etc., and should be promptly consulted and treated for the cause.
