Hi Ali,
I have had ringing in my ears about 99% of the time for the last year or so. I had to have it checked by my doctor because it was driving me crazy... My doc checked it out.... sent me to an ear specialist... neither one could find a reason within the ear for there to be this constant buzzing ringing sound. My hearing is still is as good as it ever was only thing different is that can now I hear pitches now at higher and lower levels than before RSD. Ear specialist believes, in my case, the buzzing ringing sound is a result of the RSD.
Can't hurt to have it checked... rather be safe than sorry.

Abbie
