I too have this ringing now for years. It has caused one ear to lose some of it's hearing. I try to live with it. I can't fall to sleep without T.V. on, or a headphone with music. I try not to think about it. It will drive you crazy if you fixate on it.

My husband has been diagnosed with prostate cancer state 1, but the MRI shows that it has been contained in the prostate, we are going to Johns Hopkins in Maryland, to see their Chief of Urology and he is supposed to be the expert in removing prostates and the side effects. You should call and see if there is anything else that can be done for you. Dr. Alan Patrin at Urology Dept at Johns Hopkins. Good Luck.
