Lumbar spine pain may be caused by physiological factors such as overwork, or it may be caused by pathologic factors such as acute trauma, lumbar spine pathology and osteoporosis. 1. Excessive exertion: prolonged exercise, excessive bending and other factors will lead to excessive lumbar strain, causing lumbar spine pain, which is a normal phenomenon, and the symptoms will improve after appropriate rest. 2. Acute trauma: when the lumbar region suffers from external blows or sudden sprains, it may lead to local damage to the bone or soft tissue of the lumbar spine, which will cause lumbar spine pain and soreness, and may also be accompanied by local swelling, pressure and subcutaneous bruising and other symptoms. 3. Lumbar spine lesions: such as lumbar disc herniation, lumbar spine osteophytes, etc., after the lesion is aggravated, it can cause lumbar spine pain, accompanied by buttock pain, radiating pain in the lower limbs, numbness in the lower limbs and other symptoms. 4. Osteoporosis: Lack of calcium in the body may induce osteoporosis, which may cause lumbar spine and limb pain, and in severe cases, it may lead to lumbar spine compression fracture. When the symptoms of lumbar spine pain continue to be unrelieved, it is recommended that the patient consult a doctor in a timely manner to carry out standardized treatment after a clear diagnosis, so as to avoid the continued aggravation of the lesion.
