Bad CPAP test at clinic

Hello,
New to CPAP and just went for my first CPAP test/fitting last night at it did not go well. My main problem is that I got a headache within minutes of starting the test and it progressively got worse until I had to abandon the test. It truly feels like a sinus headache.
Has anyone else ran into something like this. I was not having any sinus issue before and today I feel awful - again, I was only on the CPAP for about 2 hours.
Thanks for any help..

Hi, would like to help but there's zero info here to go on... zero. Can't address your headache or anything else without knowing more about the experience at the test, your history prior to it in any kind of detail, and what you were told on leaving. Are you going to talk to your doctor again now?

I actually had the headache happen during my in lab sleep titration study. The dumb ass tech had the mask WAYYYYY too tight.
Sinus type issues...did they use a humidifier last night?
Which mask did you try?

I remember getting a headache when I was all wired up at my sleep study. For me, I think it was anxiety.
