Lumbar paraplegia with electric shock pain may be caused by incomplete injury of the spinal cord, phantom pain and so on. 1. Incomplete spinal cord injury: paraplegia is a clinical manifestation of spinal cord injury, and spinal cord injury can be divided into two categories: incomplete injury and complete injury. Incomplete injury patients, as normal nerve fibers still remain in the spinal cord nerves, some sensations in the area below the injury plane can still be uploaded to the cerebral cortex through the spinal cord nerves, resulting in the symptom of electric shock-like pain. 2. Phantom pain: in patients with complete spinal cord injury, all sensations and movements below the injury plane disappear, but some patients can still feel electric shock-like pain symptoms below the plane, which is clinically known as phantom pain, also called central pain. The pathogenesis of phantom pain is still unclear, and it is considered to be related to the spinal cord injury itself and the dysfunction of the nervous system. Based on the symptoms of electric shock pain alone, it is sometimes impossible to accurately determine the cause, but also need to be combined with the characteristics of the medical history, other test results to make an accurate judgment, it is recommended to clarify the cause of the disease under the guidance of a doctor.
