Once that matter is settled, it is still necessary to come up with a clinical classification for itches of different types.

The itch felt is a neuronal projection of a centrally formed sensation into defined regions causing localised pruritus or into large areas of the body surface causing generalised pruritus. The afferents for mediating the itch sensation are probably a group of Cfibres with thin. Pruritus, or itch, is a common complaint in patients with cholestatic liver disease.
