Painful menstrual periods can also be the result of an underlying medical condition, such as:
Premenstrual syndrome (PMS). PMS is a common condition that’s caused by hormonal changes in the body occurring 1 to 2 weeks before menstruation begins. Symptoms typically go away after bleeding begins.
Endometriosis. This is a painful medical condition in which cells from the lining of the uterus grow in other parts of the body, usually on the fallopian tubes, ovaries, or tissue lining the pelvis.
