I'm so touched that you have all been so much help, thank you all so much
I definitely will get a second opinion, I shall ask my GP when I go on 3rd october. I have a nasty feeling that all doctors stick together, but I have to try. I'm wondering if my own CRS will miraculously see the fistula once the "guarantee" period for the operation is over!!
Andrea, we're all here for you

Good sleep and will be right as rain to fight on
