Step-by-step explanation:
The medical term for a difficult monthly flow is dysmenorrhea. Dysmenorrhea refers to painful cramps during menstruation.
Menstruation, also known as a menstrual period or menses, is the process in which the endometrium of the uterus is shed from the body if fertilization has not occurred during the preceding menstrual cycle. The average menstrual period lasts about 4 days and may involve discomfort or pain for some women. Conditions like endometriosis can cause severe pelvic pain and are associated with menstruation. Endometriosis is a disease where endometrial tissue grows outside the uterus and bleeds during a menstrual period, leading to inflammation and scarring.
