Suggest Cure For Sinus Infections

I have pain at all sinus regions on my face, also plugged ears, swollen behind my jaw/under ears, my upper jaw hurts extrememly bad. I am not congested at all, I am not coughing, sneezing, have no problems breathing. I have constant drainage going down the back of my throat which causes severe pain in my throat. I've taken antibiotics and they did not help at all. I also keep a humidifier in my room which is running constantly, I use saline nose drops. I take sudafed. All of these help minutely, but never take away the pain all together.
