Summary
allodynia is "Pain due to a stimulus that does not normally provoke pain." It is a nociceptive sensation or aversive response elicited by a normally non-nociceptive stimulus. "allo" means other, and "dynia" means pain. It can occur with mechanical, thermal, or chemical stimuli (e.g. tactile allodynia, heat allodynia).
hyperalgesia is defined by the IASP as "Increased pain from a stimulus that normally provokes pain." An example is the prick of a needle, which is normally painful, but with hyperalgesia there is a greater than normal magnitude and/or duration of pain.
