Restoring one of my senses: ability to hear?

I posted this question over yahoo and the guy suggested that I seek medical help such as doctor chit chat for medical record because maybe they have this sort of thing of medical record etc.. Here's my case

Someone has to know how, and I beg to help me :(
I'm half deaf person so I don't hear very well. As far as I was told, hearing cannot be restored or improved without hearing aid (have one) until recently something happen to me. And the same thing happen three times from my 18 year and I'm 19 year now. Never visited a doctor cause of too much hustle, and since this was strange too me, and you'll see below why.

I was playing spider man web of shadows game on ps3, while not using headphones but rather Acoustics of my room which was coming out of TV, something happen. The next morning I woke up, my head was banging and I walk in living room I could hear my aquarium's filtering machine. I thought I was making it up, but no, I could hear the water and the filter, reduced TV sound and my mom talking to me crystal clear.

I was confused, how was it possible for me to hear that good? It felt good as if having super powers.. Now here where the problem is, I'm sure that most of time when I sneeze hard enough I loose the ability to hear, since I can relate that my hearing is connected to my sinuses. I avoided any allergies and dusty areas etc to prevent loosing this newfound hearing :( unfortunately, I sneezed eventually.. :(

And I was hoping that I'll have it back, only this time I caught a cold and I could hear well, and even after the cold till i sneezed. The third time was familiar with second, but it was gone when cold was gone too.

I need to find a some way to achieve this ability, please help :(
It sure has something to do with cheekbones, swallowing, or holding breath, blowing nose.. No idea, someone must know something. I'll probably do anything, any method cause its so depressing last time I lost it

I didn't say anything to doctor cause this is all new to me and I don't think this is possible. I could never hear well and from my 7 age I carried hearing aid, so I doubt doc would believe or could do anything about it.

Please pass this to your friends, relatives.. :( maybe they know something that could mean something to me. Sure, restoring sight to blind man is a miracle, but returning hearing to deaf man is nothing special :(

Thanks for your time and reading.
