Hyperesthesia (or hyperaesthesia) is a condition that involves an abnormal increase in sensitivity to stimuli of the sense. "When a non-noxious stimulus causes the sensation of pain the area will be termed hyperaesthetic". Stimuli of the senses can include sound that one hears, foods that one tastes, textures that one feels, and so forth. Increased touch sensitivity is referred to as "tactile hyperesthesia", and increased sound sensitivity is called "auditory hyperesthesia". Tactile hyperesthesia may be a common symptom of many neurologic disorders such as herpes zoster, peripheral neuropathy and radiculopathies. In 1979, and then in 1994, Merskey, Bogduk, Noordenbos, Devor and others (a subcommittee of International Association for the Study of Pain proposed, instead of hyperaestheia the concept of Allodynia, meaning "other pain", is a pain due to a stimulus which does not normally provoke pain.
In animals
