An abnormal or pathological increase in sensitivity to sensory stimuli. Often due to neuralgia, often arising from damage to the brain (cerebral hyperaesthesia), or the spine. While there are many different types, hyperaesthesia is usually used to refer to increased sensitivity to pain.
Hearing = hyperaesthesia acustica, acoustic hyperaesthesia, or hyperacusia.
Taste = gustatory hyperaesthesia or hypergeusia
Smell = hyperaesthesia olfactoria, olfactory hyperaesthesia, or hyperosmia
Sight = hyperaesthesia optica (sensitivity to light).
Touch = tactile hyperaesthesia, hyperaphia, or hyperpselaphesia. Often takes the form of pain.
Heat = hyperthermalgesia (takes the form of pain); hyperthermoesthesia (need not take the form of pain).
Sensitivity of the muscles to pressure = muscular hyperaesthesia, or hypermyesthesia.
