Have they done anything yet?? I sent you a message and I share a very similar story. I had surgery on 8/6 and had a stent placed 8/10 for a stricture. It did help although I am still nauseous and miserable (in part maybe from the stent), but SO much better then I was initially. They need to do something for you if they haven't yet.
So sorry you have to go through this.
