It is possible to recover from a spinal cord injury after five or six years. Patients with different degrees of spinal cord injury can recover and the time of recovery is also different, so we cannot generalize. 1. Spinal cord shock: it is a mild spinal cord injury, only function is impaired, usually after a few hours or 2~3 days of functional inhibition period, the function is slowly recovered, and most of them can be fully recovered within 6 weeks. 2. Cervical cord injury: Thoracic cord injury and lumbar cord injury leads to incomplete transection or even complete transection, and patients with sensory impairment and paralysis below the damaged plane are more difficult to recover, and it often takes 3~6 months, or even difficult to recover for the rest of their lives. 3. Cauda equina injury: most of the patients can recover after active and effective treatment after the release of pressure, and the recovery time ranges from 3 months to several years. Patients with spinal cord injury should seek medical treatment in time and follow the doctor’s instructions to avoid delay.
