As most of the ladies can agree, that being in the menstrual cycle is very inconvenient. But there is a condition which this not only inconvenient but very severe and intolerable. Endometriosis is the specific condition which the famous actor and writer Lena Dunham were diagnosed with. It is characterized by the growth of endometrial cells in other areas of the abdomen, not the inner lining of the uterus. She has fought with it for years and has been very open about it as well.
