If you recall, 6 weeks or so ago, on a whim, I took wee difficult child's neuropsyche report to my allergist/immunologist just to ask if he thought he had anything to add, and he agreed to see wee difficult child. He was very up front in saying he didn't think he could cure him, but he was going to look into any areas he thought he might be able to make improvements - the hope being that some little fixes may make things more tolerable. In addition to setting up a complete second opinion, they put difficult child on a pulsox for a few nights. They called today with the results. His O2 sats are falling into the 60's repeatedly thru the night! They are contacting another doctor, so we'll find out the next step in the morning, but surely this can be improved!
