Hi, my friend is fearful to go back to her doctor because she said all they do is do tests and more tests and don't fix her problem. She's told me a little about her symptoms and I think she has a rectal vaginal fistula. She's afraid she's got cancer so she won't go back to the doctor. What do they do for a r/v fistula? Is it a huge surgery? I'd like to be supportive of her and encourage her to get it repaired.
