What should I do if my hand hurts badly after an electric shock?

After an electric shock, if the hand feels very painful, the discomfort can be relieved with local heat application or massage. The patient's arm numbness and soreness may be due to local muscle or nerve damage caused by the electric current; it is also important to check whether there are other bodily discomforts, especially related to heart and lung function. When necessary, a hospital visit for an electrocardiogram (ECG) is recommended. If soreness persists, medications that promote blood circulation and nourish the nerves may be taken.
