Pain responsivity in women with premenstrual syndrome across the menstrual cycle.
11 women with a clinical diagnosis of Premenstrual Syndrome (PMS) and 10 control women with no such diagnosis were compared on pain threshold and pain-tolerance measures in the intermenstrual and premenstrual phases of their menstrual cycles. No significant differences were found between the groups for behavioral measures of pain sensitivity. Ratings of pain intensity, however, were higher in both phases for the PMS group.
