Sinus Medication Solution

Anti inflammatory meds seem to help, but my body gets used to meds so they stop working.When air pressure drops,so do I from reality.I used to have migraines,so I know these are not migraines
Spring,fall,last 2 weeks of the year & 1st 2 weeks of the year are the hardest times for me
Right before rain is here (storms are worst!)Bad times also when I’m dizzy,nauseated,& weak.Sometimes I collapse in weakness.At times my ear canals ring,feel pressure or even hurt.
Drs just give me antihistamines,which sometimes work on allergies,but never for sinuses.The only time I ever get sinus infection is when I have this 3 days.But these headaches almost always last 4-6 hours.No comfort,no relief
Airplane take off/landing make me real dizzy,&I feel sinus pressure start.It’s gone soon after landing
As a kid, in elevators,I would squat in the corner with my head in my hands.I’m adult now,still get a bit dizzy,but not bad.I have more body mass
Any ideas?
Correction, the headaches last 4-16 hours

I have a large painful lump above my gum towards the back. It has no puss. I need to get some relief right away. Do I go to the dentist or could it be sinus related? Dentist or Doctor?

I have a build up in my throat, right at the clavicle that causes me to clear my throat constantly while speaking. It was very annoying and embarrassing. I’ve been to several doctors and without even looking at me, they prescribe flonase and allegra or zirtec, none of which works for this problem. Any suggestions? It just sits at the base of my throat and makes itself as annoying as possible and I can’t really cough it up well either. Once in a while if I drink lemon juice and salt straight, I get some manner of relief for a little while, but it never breaks up completely.
