Yes it's REAL bummer.

Unfortunately Tinnitus is one of the few symptoms that does not resolve.

Mine came on 2 days after the accident.

Were you by any chance placed on any prescription medications when you were injured?

I was placed on MOBIC and PERCOCET. I'm not sure they triggered the TInnitus however i'm suspect to ANYTHING.

I don't think MOBIC or PERCOCET were GOOD for me since I had a head injury in addition to back/hand injury.
