Hey sweetie! You have really been up against it lately(!) Hope you are getting nice rest. Those kinds of things can be so tedious and wearing. Good it's not the gallbladder, but you're right -- it sure does leave it frustratingly mysterious, and you've had more than your fair share of that already (like when they kept not figuring out the gluten thing). Hope you get to feeling better soon and getting some answers (of the easy-to-fix variety!) without too much go-around.
