I talked to the nurse at our peds office, and she said that the test results were marked "unremarkable" (a good thing!) but that the GI specialist has not reviewed them yet.
So we just chill until Monday and Tuesday! While I would be totally ecstatic to learn there is no issue that requires surgery, it makes me wonder what the heck this could be then? They mentioned intolerance, but as far as I can tell, that should cause constipation or diarrhea, I haven't been able to find anything that says it would cause these motility issues.
Anyway I guess there is no point in speculating. I just want to figure out what this is, whatever it is, so we can move on to the next step of fixing it.
