Endometriosis is a painful condition that affects mainly women... and it takes an average of 8 to 10 years for women to be successfully diagnosed. The new documentary "Below the Belt," executive produced by Hillary Rodham Clinton, takes a look at four women struggling to get properly diagnosed and treated for their endometriosis. Director Shannon Cohn joins us to discuss the documentary, which you can stream through PBS, and take calls from our listeners about their struggles with endometriosis.
