Had this diagnosed on Wed and my right ear is completely blocked. The hissing/ringing noise is driving me mad :-( Is my hearing likely to come back gradually or will it suddenly clear? My balance is really off too, and I don't think driving would be a good idea. I'm a bit concerned about going back to work on Monday feeling like this, but on the other hand I can't stay off for weeks if my hearing isn't going to come back quickly! Any advice/experience welcome.
