Hi.  recently, roughly in the past few months, i have been
experiencing a rumbling sound in my left ear, it feels like my ear
drum is spasming or something like that.  The thing is this, until
about a month ago, i wud only get this sound if i was lying down on
the left ear.  If i heard the slightest noise, the rumbling would
start, then go as soon as the noise stopped (usually my brother
tossing and turning in bed, above my room).  A month ago i was just
sitting using my pc and my left ear went mad...about a minute of
extreme rumbling, i was kinda panicing a bit cos it wudnt stop (this
was sat up, not lying on left ear as when the rumbling usually
occurs).

Does anyone have any idea what could be causing this?  i often listen
to loud music and wonder if i may have damaged my eardrum?  but my
right ear is fine so it may not be due to the music. Tinnitus maybe?

help would be much welcome :)
