Phénoménologie expérientielle de l'algie vasculaire de la face (AVF)

The EI have allowed us to describe precisely the painful experience of subjects with a cluster headache. This experience is very rich and very intense. EI, as a phenomenological method, is a very useful method to describe more precisely the symptomatology of a disease, because it pays attention to the effective experience of the pathological flesh, as compared to the pathological body.
