Primary dysmenorrhea is characterized by painful menstrual cramps that typically start at the onset of menses and often radiate to the back and thighs. These cramps are caused by the contraction of the uterus as it sheds its lining. The patient often complains of abdominal bloating and may present with systemic symptoms such as dizziness and headache.
Secondary dysmenorrhea, on the other hand, is caused by underlying conditions such as endometriosis, pelvic inflammatory disease or fibroids. The pain can occur also during ovulation and may be accompanied by other symptoms such as heavy bleeding or abnormal discharge.
