NORTH CHICAGO, Ill. (CBS Local) – The FDA has just approved a new treatment for a condition that feels like “tiny people skating on razor blades in your stomach,” according to millions of women.

“Endometriosis is often characterized by chronic pelvic pain that can impact women’s daily activities,” Dr. Hugh S. Taylor from the Yale School of Medicine said in a press release. Drugmaker AbbVie added that the debilitating pain caused by this condition affects one in 10 women and can sometimes go undiagnosed for up to a decade.

Michelle Kinney, whose had surgery three times for the severe period pains, told Business Insider that the pain felt “like little people in side her skating around on razor blades and other times like someone’s poured gasoline inside.”
