....what this means.

I constantly (all day long) hear the sound of a little drummer boy in my right ear. It kinda feels like the muscle in my inner ear is twitching and i hear a rumbling sound. Also, like one to two times a day, for no reason, my hearing goes halfway mute, instantly and slowly fades back with a ring much like (to those of you that know) when an explosion hits, except its not as pronounced and of coarse, and as im in germany, there are no explosions.
