Back pain in the middle of the spine

Pain in the middle of the back spine can be caused by a variety of causes, including muscle strain, spinal disease, spondylitis, intraspinal disease, infection, and other factors. 1. Muscle strain Maintaining poor posture for a long time, excessive weight or strenuous exercise can cause muscle strain in the middle of the back spine, causing pain. This pain usually relieves after rest, but it easily recurs after fatigue. 2. Spine diseases such as spinal fracture, disc herniation, scoliosis, etc. Spinal fracture will directly cause pain, especially during activities or stress; disc herniation can compress nerves and cause radiation pain; scoliosis may cause imbalance of muscle strength on both sides of the spine, causing pain. 3. Spondylitis includes ankylosing spondylitis. This disease can cause chronic inflammation of the spine, resulting in pain, stiffness and other symptoms, and the disease may gradually progress.4. Intraspinal lesions such as spinal stenosis, spinal cord tumors, etc. These lesions can affect the spinal cord or nerves, causing pain in the middle of the back spine, and may be accompanied by lower limb numbness, weakness and other manifestations. 5. Infections of the spine, such as spinal tuberculosis, can also cause pain, and may be accompanied by systemic symptoms such as low fever and night sweats.6. Other factors Some visceral diseases, such as heart disease, cholecystitis, etc., may sometimes radiate to the middle of the back spine to cause pain, but usually accompanied by other symptoms of the corresponding visceral disease.
