Loss of Hearing And Sinus Infections

For the past 3 years between october and april, I get a sinus infection. I go to the doctor who just gives me antibiotics. Last year after suffering for 4 months they sent me to an ent for allergies testing. I don't have any allergies at all.

This year it started out as a sinus infection. I would cough alot, get headache's all the time, my nose would bleed and have alot of drainage. I started getting sharp pains inside my ear and when I went to the doctor they said that the infection has backed up into my ear and that my ear drum has ruptured. I can no longer hear out of my left ear at all. They said it would heal on it's own and gave me another prescription for antibiotics. I feel sick all the time because of the drainage. I went back to my doctor 3 times in a week and all they do is give me another prescription for antibiotics. Nothing seems to help. I'm going to see an ent doctor on tuesday, but I was wondering if anyone could help me be able to explain to the ent doctor what is going on. Any advise or information would really be appreciated.
