Help with hearing problems

Maybe this is as off topic as it can get but with bad hearing there not much joy with a real good hifi system.

The problem is that my ears are plugged most of the time and it is affecting my hearing a lot. Most music sound hard so right now it's all soft jazz (:

I have visited 3 different doctors and they all took the same measurements and came to the same conclusion, that they couldn't find anything wrong. They could see that my hearing was affected on the left ear but later on I got another hearing test and my hearing was okay. I was expecting the second test would show that everything was okay because I wasn't having any problems with my ears at that time.

The problems with my ears started 3 years ago after a real nasty could. In periods lasting around a month everything has been fine. But for the last 5 months my ears have really been bad.

I have tried different ways to “blow” my ears and Googled a lot, but I am desperate now and grasping for every straw I can find.

Any help in any form is much appreciated.
