<unk>  is a condition in which pain is caused by a stimulus that does not normally elicit pain. For example, bad sunburn can cause temporary<unk> , and touching sunburned skin, 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 is from Ancient Greek άλλος állos "other" and οδύνη odúnē "pain".
