Hi, Christina,
The pediatrician is on the ball enough to refer you to U. Mich if necessary. That is good news. I suppose it is also good news in a way that they did not find anything in the UGI biopsy. Still, it will be nice to have answers.

It looks like you have dr shopping to to through.
I need to work on that too. I don't know why I would rather put up with bad to mediocre than get on the phone.
Maybe getting on the phone is easier when it is for someone else, like your own son.
Good luck in getting good drs and in getting the tests you need.
You have been busy.
