Hi. I have had tinnitus since 2011. I do not know how or why I got it, but I did . In the beginning, not only did I have both ears ringing, I also developed hyperacusis. The ENT specialist I saw in my state told me it is not a life threatening "thing" and I should learn to live with it. After several months I finally got an appointment at The House Ear Clinic in LA. The doctor there was awesome. She told me about clinical trials, neuromonics and an over the counter supplement called NAC. Immediately I started on 600 mg of NAC twice a day. In about a month, the severe hyperacusis stopped completely along with the ringing in the right ear. As of today, I continue to have cycling tinnitus in my left ear. I continue to take NAC daily even though I have not had any change since the hyperacusis and the right ear ringing stopped years ago. Since then I have tried so many things and not one has worked. THINGS THAT HAVE NOT WORKED Braces(again in case it might have been tmj) Neuromonics (1 year) Acupuncture(4x week for 6 months) Ashwagandha Extract(GNC store 1 month) Lipoflavonoid Plus (GNC store 2 months) Ginkgo Biloba (GNC store 2 months) Dark Cherry juice(GNC store 1 month) Cider vinegar(GNC store 1 month) THINGS THAT HAVE WORKED NAC- alleviated hyperacusis and right ear ringing during the 1st month of starting it BUT nothing since then. I was also rejected from two clinical trials because I did not live in the state. Their reasoning was if I received a placebo or if the treatment was not working I would not continue with the trial. So, here I am today with an ear that still rings 9/10 on a scale and a son in medical school that will hopefully find a cure for this "thing" called tinnitus that his mother suffers from.
