Some science behind the scenes

Hyperaesthesia

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 peripheral neuropathy and radiculopathies.

 

Hyperesthesia  - its causes and the observations associated with it are treated in the more general section Nervous system diseases.
