ear problems, ...am i going deaf? Options

[pink.x.r0se]

i've been sick since around the beginning of spring break, just a coug and a runny nose, but since it lasted so long i've been to the doctors a couple of times. they've never really given me a straight answer on what's wrong but both times i was told i had a sinus infection. the cough and runny nose i still have, but it's gotten a lot better. but a few weeks ago i noticed that my right ear's hearing seemed dulled and it felt like i had to pop it but i couldn't until a few days later. it REALLY hurt but i could hear normally again. but even since then, my ear would pop painfully every so often.

now, my ears pop whenever i yawn. and when i eat, my chewing sounds so loud to me that it completely drowns out anyone who's talking to me; if i can't see that someone's talking to me, i won't know AT ALL. the same thing happens after i excersize, except for that my heart's beating/my breathing is too loud.

any ideas on what this is and if its connected to te sinus infection?
