High-fat diets induce hyperalgesic priming, a neurological change that represents the transition from acute to chronic pain, and allodynia or pain resulting from stimuli that do not normally provoke pain.
Sociodemographic factors, such as depression, medication overuse, allodynia, and income, are linked to migraine chronification.
Neurologists at the University of Michigan reveal why some people get headaches when wearing their hair in ponytails. According to researchers, ponytail headaches are an example of allodynia, a normal stimuli interpreted as painful. A lack of sleep and a predisposition to migraine are some factors that may make the experience of pain worse.
