Jeez, sorry to hear that! Will it get better? Were IPA vapors the incontrovertible cause?
I ask because I, too, spend a lot of time in the same room as my Form Wash and rinse gear. I had some sinusitis-like symptoms several months ago, they went away, then came back a couple times at maybe month long intervals. Never figured out what caused it. I considered IPA Vapors but was skeptical as I didn’t notice a direct correlation between when I printed/rinsed and when the symptoms presented (although I wasn’t anywhere near scientific about it).
I picked up a 3M respirator with organic vapor cartridges (6001 black or 6003 yellow) and try to use it when I’m working right overtop of the rinse station.
BTW here’s what I said in the other thread (aside from the gasket complaint, I like the Form Wash):
