You likely have Villar's nodule, and a simple surgical excision can end the cycle for good.
Belly button endometriosis, clinically known as or Villar's nodule , is a rare form of superficial endometriosis where tissue similar to the uterine lining (endometrium) grows within or just beneath the umbilicus.
When most people think of endometriosis, they imagine pelvic pain, heavy periods, and fertility struggles. They rarely, if ever, think of the navel. Yet, for a small but significant group of women, the belly button becomes a monthly source of mystery, pain, and bleeding.
