Anesthesia is the answer. Anesthesia reduces pain as well as preventing it.It enables a painless performance of a procedure causing too much pain if no anesthesia is given. Categories include general in which the patient is unconscious, regional which blocks an area of one's body and local anesthesia that causes numbness in a small area.
