Peripheral nerve injury usually has symptoms of sensory, motor and autonomic dysfunction, and peripheral nerve injury is usually complete. Multiple peripheral neuritis can be divided into acute, subacute, chronic and recurrent according to the course of disease. Typical symptoms of peripheral neuritis include symmetrical sensory loss in the distal extremities, which extends from the distal to the proximal. Sensory impairment refers to the abnormal sensation from the far end of the limb, such as the sensation of acupuncture, ant walking, or burning, tenderness, etc. In addition, the sense of symmetry at the distal end of the limbs may be decreased or missing, usually in the form of gloves and socks. The movement disorder of peripheral neuritis is mainly manifested as symmetrical muscle weakness at the distal end of the limb, which can be manifested as mild paralysis, or even complete paralysis, and there are low muscle tension, weakening or disappearance of tendon reflex.
