Dysmenorrhea
Also known as menstrual cramps, dysmenorrhea is the clinical name of a type of throbbing pain in the lower abdomen that interferes with the daily lives of the patient and appears during menstruation. Patients with fibroids also get menstrual cramps before or during the menstrual cycle. These cramps occur because of a strong contraction of the uterine muscles that results in decreased blood supply to the structures below the uterus. Pain may be located in the belly, the upper and lower thighs, or the lower back.
