Quantitative sensory testing (QST) is a robust lab paradigm (not a clinical experience) that delivers one painful noxious thermal stimuli and asks for simultaneous pain intensity and pain unpleasantness scores. By using this in the research, investigators will be able to differentiate the sensory (pain quality—what the pain feels like) from the affective (how awful/unpleasant the pain feels) components of experimental pain in normal controls vs. migrainuers.
