Allodynia

Allodynia
Specialty	Neurology

Allodynia is a condition in which pain is caused by a stimulus that does not normally elicit pain.^[1] For example, sunburn can cause temporary allodynia, so that usually painless stimuli, such as wearing clothing or running cold or warm water over it, can be very painful. It is different from hyperalgesia, an exaggerated response from a normally painful stimulus. The term comes from Ancient Greek άλλος (állos) 'other' and οδύνη (odúnē) 'pain'.
