Keep the appointment with the rheumy, but, in the mean time, please consider making an appointment with a GI specialist as well. If you see a GI doctor, let him know about the hiatal (sp?) hernia diagnosis and the symptoms your husband is having. He may feel it warrants and upper GI study.
You are doing the right thing by doing research and not accepting the first opinion you get. This is your husband's health you are dealing with. My cousin had major GI problems as a pre-teen. None of the doctors could figure out what was wrong with her. I told her mom to please see a pediatric GI doctor because I felt like her symptoms matched Chrons to a "T". Well, she spoke with my cousin's primary and he said, "No, kids don't get Chrons. That kind of thing shows up in the early 20's or even later." Guess what- she finally went to a GI and surely enough, my cousin did/does have Chrons.
My point is, you keep searching until you find an answer. The more research you do, the better chances you have of understanding how to help the doctors to help you to help your husband. There is nothing wrong with an informed patient.
Please keep us posted. I do hope you find the answer soon, and I am also sending wishes and hopes that this will be something that will be taken care of swiftly so that your husband can stop feeling so bad.
