Your GI doc is not helpful saying things like that. It's not an untypical comment, though. Specialists do their tests, come up with their results, tell you what they discovered, brush their hands together with satisfaction, and send you on your way to fend for yourself. Do you have a good family doc or internist? If you do, he/she might be your best bet right now. They tend to look at the whole person, and try to interpret what is happening so they can help you.
Did you call the GI regarding your burning symptoms after Carafate? If it makes you more uncomfortable, your inflammation and irritation must be so intense that your throat and stomach are raw. It would be very interesting to hear what the response would be regarding taking in with those symptoms.
Specialists give you their opinion and send you on your way. It's not a real long-term relationship. Those of us who don't respond to easy solutions are frustrating to these guys.
Find yourself a GREAT primary care doc.
I hope you're feeling better today! Hang in there.
