Sequelae of injuries

PNT cases such as allodynia, in contrast, occur not only with tissue damage but also often occur in a site where there was an injury that has healed. A non-noxious stimulus to the site or an area surrounding the site produces pain. The mechanism for this could be the local sprouting, during the healing process, of excess nerve terminals, and/or permanent changes in the sensory system leading to the cortex that have nothing to do with cognitive mechanisms associated with threat that are activated in the case of PCT.
