I Have Sinus Ache Behind My Nose Followed By Nausea,

I have sinus ache behind my nose followed by nausea, with smell sensitivity of smoke when no one else in the house smells smoke, then on comes dizziness and I have notice my vision for reading has significantly changed about a few months ago to which I have had to get reading glasses. My Ear, Nose, and Throat specialist ruled out any sinus or inner ear problem and referred me to my GP for possible migraine that might be causing all these recent systoms?
