General discussion is a good place. May I suggest that you start a new paragraph for each new surgery or complication? It is difficult to follow the story in one huge flow of worrds like that.
It seems that you have had a multitude of serious complications. Sometimes, minor misjudgements turn into huge complications. Once you are weakened, you are sort of "set up" for a cascade of unfortunate events.
Having a Crohn's diagnosis would help make more sense of this, but it sounds like they have not seen evidence of it, at least not yet.
The problem with fistulas is thet sugical repair is not always successful. And, with you being in a more or less critical state, it puts you at further risk. So, now that it has been a long time, it is appropriate to think about going in and getting it fixed. I imagine that for you, the challenge will be finding a surgeon you trust, and with your history there may not be many willing to try.
I hope you find the right doctor.
And speaking of your nerves, are getting help for that too?
