Thank you so much for your replies, I'd have perferred something along the lines of: no, that doesn't sound like a fistula, or: no way you have CD... ;)
However, my past has caught up with me, and now it feels like I'm moving into a new phase of ill health after having had 30 years of ups and downs with the pouch, but at least the ill health has, up till now, been contained.
I hope my family doesn't suffer too much, as for me, it seems it is my fate.
Very sad today,
