@eighteen : if it's just getting worse you need to see a doc, I had pain like that back in 2013 and postponed a visit to the doctor because of the cost, when I did go she prescribed the completely unsuitable cephalexin which just made it flare up.
I ended up at the ER in agony and I was admitted because they were worried the infection may track back up my optic nerve to my brain.
There was no on call ENT at MH northeast so they took me to the medical centre and kept me in two nights, pumped me fill of steroids and antibiotics. The morning after my first night in hospital my eyes were swollen shut but it cleared up rapidly after that.
Sinus infections are not worth messing with and you at least need to rule out an infection, you won't clear it up without real antibiotics if you have one. If you go to a family doc insist on something heavy duty like Augmentin or a Z-pack because amoxicillin and cephalexin are not gonna do the trick.
