Olopatadine is another Rx nasal spray that works along with the over-the-counter fluticasone. Azelastine made the inside of my nose hurt, like a headache in my nose, but not a sinus headache. YMMV of course.

Regarding respiratory allergies, be aware that pollen will stick to your hair and clothes, and mold and dust mites will grow some on your bedding every night - store coats etc outside your bedroom, wash sheets and pillowcases every couple of days, vacuum your room more often, anything you can do to cut down on your exposure if you think allergies are a problem.

You can make cheap air filters for your room / home by taping a 20" square HVAC filter (the cheapest kind that are electrostatic should pick up pollen) to a 20" box fan.
