I had something similar for a while. It lasted a long time but it did eventually go away by itself.i think i've gotten tinnitus. i keep hearing weird rhythmic peeps in my left ear when i lay in bed. they sound a bit like the cry of a seagull from far away. at first i thought i had a mouse in my room but it's only in my left ear. the weird thing is though, i haven't been exposed to any loud noises or music the past year.
