Lumbar lateral subcostal pain may be caused by trauma, local inflammation, cholecystitis and other reasons. 1. Trauma: the symptoms of lumbar subcostal pain can occur when the patient suffers from rib fracture and surrounding soft tissue injury due to external trauma. 2. Local inflammation: due to infection or long-term strain injury caused by local inflammation in the ribs, stimulating the surrounding soft tissues to produce the symptoms of lumbar subcostal pain. 3. Cholecystitis: cholecystitis is mostly caused by gallbladder stones, bile discharge obstacles, causing the gallbladder to increase in size, resulting in lumbar subcostal pain. Lumbar subcostal pain can also be caused by lumbar disc herniation, kidney stones and other causes. It is recommended that the patient should go to a regular hospital in time for consultation, to clarify the cause of the disease, under the guidance of the doctor for treatment. Do not ignore the symptoms, so as not to cause adverse consequences.
