an unpleasant sensory experience that travels a multisynaptic route to the brain via slow-conducting, non-myelinated nerve fibers.
Pain that is perceived a second or more after a stimulus. It is transmitted to the central nervous system by C (nerve) fibers, which are not myelinated, and therefore conduct sensations more slowly than A delta fibers. Slow pain lasts longer than sudden pain. It is usually perceived by patients as burning, cramping, dull, itchy, or warm.
