In addition, a neuronal hypothesis has been advocated for the pathogenesis of primary dysmenorrhea. Type C pain neurons are stimulated by the anaerobic metabolites generated by an ischemic endometrium. Women with dysmenorrhea appear to have enhanced pain sensitivity compared to women without dysmenorrhea, even during phases of the menstrual cycle when they are not experiencing menstrual pain. [15] This enhanced pain sensitivity may increase the risk of affected women to other chronic conditions (eg, fibromyalgia) as well as negatively impact their quality of life. [15]
