Allodynia refers to central pain stimulation usually following a non-painful stimulus. There are many types of allodynia, including mechanical (static or dynamic; pain in response to being touched), thermal allodynia (pain from ordinarily mild temperatures in contact with the affected area), and movement allodynia (pain that is triggered by normal movement of muscles or joints).

1. Allodynia Symptom: Pain

Pain is the primary symptom of allodynia, caused by stimuli that don’t usually cause pain. A person may find cold or hot temperatures painful. They might also experience soreness from gentle pressure or touch on the skin. Some might even feel pain in response to a brushing sensation or another movement along the hair or skin.
