Yes, I think sinus problems tend to be easier to manage than cluster headaches, don't they? (I'm clearly no expert...)
If it helps, I wish our good K teacher had leveled with us and told us that the school couldn't (or, to be more accurate, wouldn't) give DS7 what he needed. It's hard to hear that, and I know your work situation makes homeschooling less than ideal (!), but assuming it's the truth, I suspect you might end up grateful for her honesty. I know I would have been when we were trying to figure out what to do.
All the best to you! Hang in there!
