Two sequential pain sensations in short time intervals is the result of sudden painful stimulation. The first one is immediately after the damage. It is followed several seconds later with additional pain sensation. These two separate sensations are several seconds apart because a fast transmitting information sensation is carried via A delta fibers and is followed several seconds later with slow transmitting pain information carried via C fibers. This phenomenon is known as “double pain sensation”
