Injury to a spinal nerve with no sensation in the leg can usually be recovered if the nerve is not broken and can be treated promptly and correctly, but if the injury is severe enough to cause the nerve to be completely broken, recovery is usually impossible. If the spinal nerve injury is caused by trauma and the nerve is not broken, and after timely and correct treatment such as decompression surgery, it is usually able to be recovered; however, if the spinal nerve injury is serious and results in the nerve being completely broken, resulting in the leg not being able to feel, or even paralysis, it is usually not recoverable. If the spinal nerves are injured and there is no feeling in the legs, it is recommended to go to a regular hospital in time, complete the relevant examinations, make a clear diagnosis and then follow the doctor’s instructions to carry out targeted treatment, so as to avoid delaying the condition.
