I had a fall and my back hurts, it doesn’t hurt when I’m standing and it hurts when I’m lying down. It may be due to internal organ injury, lumbar vertebrae fracture, soft tissue injury and other reasons. You should immediately go to the hospital for examination to exclude organ damage, and then according to the results of the examination for conservative treatment or surgical treatment. If you have fallen and your lower back doesn’t hurt when you are standing and it hurts when you are lying down, you must be properly examined to determine whether there is an abdominal organ injury. If there is an organ injury, you should go to the general surgery department and be treated according to the severity of the injury (if the injury is not serious, conservative treatment can be used to prevent hemorrhagic shock; if the injury is too serious, surgery may be needed). If there is no organ damage and no fracture of the lumbar spine, then only symptomatic rest and the use of non-steroidal anti-inflammatory drugs (e.g. celecoxib) for pain relief are necessary. If there is a fracture of the lumbar spine, and the fracture is mild and without serious complications, conservative treatment is an option. If the condition is more serious, surgery is needed. However, the use of drugs should be under the guidance of a doctor, and must go to the hospital for a comprehensive and proper examination and treatment, to avoid delaying the condition.
