I most certainly agree, Duffybear...That was my first flare in 2013, I expected it to be very similar to what I'd already experienced (starting with scleritis and then ears and sinuses). Thus, all the sinus issues and no eye or ear involvement got me very puzzled, we waited for months until it got too bad, then I realized how silly and irresponsible it was...
The disease and its symptoms can easily trick anyone, making it confusing, painful and frustrating, but the diagnosis speaks for itself and has to be considered if anything weird is occurring...
Long story short, after lots of research I now have a vasculitis specialist taking care of me, so I hope I'll avoid severe flares and will keep everything under control!
