One of the causes of low back pain: it is caused by diseases of spinal joints and their surrounding soft tissues. Such as lumbar muscle strain, myofibrositis, local injury, bleeding, edema, adhesion and muscle spasm caused by contusion and sprain.
The second cause of low back pain: due to spinal lesions. Such as rheumatoid spondylitis, hyperosteogeny, tuberculous spondylitis, spinal trauma and lumbar disc herniation.
The third cause of low back pain: spinal cord and spinal nerve diseases. Such as spinal cord compression, acute myelitis, radiculitis and spinal cord tumor.
The fourth cause of low back pain: diseases of internal organs. Such as nephritis, urinary tract infection, urinary calculi, cholecystitis, cholecystolithiasis, pancreatitis, gastric and duodenal ulcer, prostatitis, endometritis, adnexitis and pelvic inflammatory disease. Tumors can also cause lumbosacral pain, and female patients are often accompanied by corresponding gynecological symptoms.
The fifth cause of low back pain: due to mental factors. For example, hysteria patients may also complain of lumbar diseases, but there are no objective signs, or objective examination and subjective narration can not be explained by physiological anatomy and pathological knowledge. This kind of back pain is often a sign of hysteria.
