Why do uterine fibroids cause painful menstrual cramps?

Rafael J. Perez, MD
OBGYN (Obstetrics & Gynecology)
Fibroids can be painful to some patients. Uterine fibroids can cause inflammation on the uterus, which can lead to painful menstrual cramping. Also, the passage of blood clots through the cervix can cause painful menstrual cramps. Each patient is different.
Fibroids can cause pain in 2 distinct ways:
  • By causing heavy menstrual flow which includes passage of blood clots. When these clots travel from the uterus through the cervix in to the vagina this elicits pain.
  • Fibroids that are large enough to press on adjacent pelvic nerves can cause pelvic pain which can radiate in to the lower back, hips, buttocks, and even down the legs.
