Numbness due to spinal cord injury is a common symptom caused by nerve injury, and the recovery time is within six weeks or more than three to six months, or even lifelong, depending mainly on the degree of injury. Minor injuries such as spinal cord shock are generally not serious and slowly begin to recover after a period of inhibition of a few hours or two to three days, usually within six weeks. Incomplete transection and complete transection of the spinal cord, which occurs at the cervical, thoracic or lumbar level, is a serious injury that takes a long time to recover from because of severe violence, usually taking more than three to six months, or even a lifetime. Numbness caused by spinal cord injury is recommended to be treated under a doctor’s supervision and in accordance with medical advice.
