Physiological reasons: the above area is covered by thick muscle tissue as well as fascia, if the patient maintains a fixed posture for a long time, and performs stooping labor for a long time, it may lead to fatigue injury and aseptic inflammation in the lumbar area, resulting in pain; cold stimulation will lead to local vasoconstriction, muscle spasm, and metabolite accumulation, and it may also lead to pain symptoms. 2. Pathological causes: diseases of the lumbar region itself may also cause pain in the lumbar region, such as lumbar disc herniation, acute lumbar sprain, lumbar three transverse syndrome, etc.; secondly, when the right lumbar deep organs are diseased, it will also lead to the above symptoms, such as the right side of the ureteral stone, the right side of the kidney stone, etc.; female patients also need to be alert to whether it is a result of gynecological diseases, such as the right side of the tubes, the right side of the adnexitis and so on.
