Yes, us poor souls!
I have a small/mild/light fistula (in my opinion) because the discomfort associated with my fistula is minor enough that it is not worth sacrificing the functionality of my amazingly well behaved pouch with any type of repair.
I take one heaping teaspoon of metamucil each morning in a small glass of OJ to bulk me and that pretty much takes care of my symptoms. On days that I don't take the metamucil I notice much more discharge. I wear a panty liner every single day, and that is the extent of my inconvenience. I must keep clean, or I tend to get irritated.
Fun? No! Manageable? Yes!
