Pain is a very common complication after spinal cord injury. We often encounter this situation in our clinical work, and some patients even need to use analgesic drugs for a long time. According to some overseas statistics, more than 60% of paraplegic patients suffer from various kinds of pain caused by spinal cord injury. According to a survey in Britain, 11% of paraplegic patients lose their working ability not because of the motor disorder caused by paralysis, but because of pain. According to some other data, 23% of patients with low-level thoracic or lumbar cord injuries are suffering from severe pain, and they even fantasize that “if I can avoid pain, I would rather not have other functions, such as sexual function, bowel control, etc.”. What are the causes of pain after spinal cord injury? After spinal cord injury, scarring in the spinal canal causes compression of the posterior horn of the spinal cord (the area that governs sensation); 2. Scarring of the spinal cord in the injured section, and contracture of the scar causes pulling of the spinal cord above the level of the spinal cord injury; 3. Mental and psychological factors.
