I Have Vaginal Fistula Or This Is Best Description I

I have vaginal fistula or this is best description I have found for hole that seemed to appear overnight some 3 years ago. I have care for this hole as it do allow fecal matter to pass through it. When it first appeared it took little while for matter to pass through it and I guessed my body tried to repair it and the tunnel got shorter as body tried to repair it.
