Sorry to hear about the trouble your going through, but happy to hear that all worked out.
I'm going through a similar issue with my doctor. I had surgery 3 weeks ago, and am having some complications. My surgeon ordered a specialty CAT Scan and the amount of hoops I had to jump through was ridiculous.
Going back to see him today... Hopefully no issues.
Sorry for the thread jack and rant

Hope all works out for your boy !!
