I Have Been Taking Amitriptyline For Help Of Sleeping, And

I have been taking amitriptyline for help of sleeping, and it does seem to help, also for some time now opana for back pain after fusion and other herniated discs that I must deal with because they are in the thorasic area. The amitriptyline now only a couple months and I have noticed some ringing in the ears? I now just saw it as a possible symptom of use. Will this go away as I stop taking it? I will discuss further with my Dr. next visit.....
should I be worried about it?
