Knife damage to a nerve can have both immediate and delayed manifestations.
If the knife damage to the nerve, will lead to the patient to appear in the corresponding innervation area of the electric shock-like sensation, radiated pain or numbness, and relatively speaking, it will be more intense, when the removal of the knife, this feeling will gradually disappear.
If the nerve injury is more serious, the intense radiation-like, lightning-like pain or numbness, it is difficult to subside in a short period of time, the more serious cases will appear within the innervation range of muscle weakness, or even muscle atrophy, sensory abnormalities or loss of sensation.
If the nerve is injured by the knife, the treatment should be stopped immediately and treated under the guidance of a doctor.
