I have discovered something that has cured my sound sensitivity, it is TINNITUS RETRAINING THERAPY. I had HORRIBLE sensitivity to sound, and tinnitus retraining therapy SAVED me. The sensitivity was so bad that I was literally on the verge of ending it all, I thought there was no hope, I thought there was no chance it would work, but I had to give it a shot, and it WORKED. I highly, highly, highly recommend it to all CFS patients suffering with sound sensitivity (hyperacusis). It works for all types of sound sensitivity, no matter the cause. It is the only CFS symptom that I have ever been able to improve. If sound sensitivity is something you are struggling with, please please please try tinnitus retraining therapy. I did it without spending a dollar. All I did was listen to this video in headphones at a level so low that if I turned it any lower it would not be audible. And I listened to that for every moment of the day that I could, and then when I would get used to it and forget I was even listening to it, I would turn the volume up one, and I just continued that process, but then when I was up to a reasonable volume on that video, I switched over to this video and did the same thing with that video, starting from a barely audible volume and working my way up. I spoke with an audiologist about this, and she said that it is all about retraining the brain's involuntary emotional response to sound. We need to re-teach our brains what a normal level of sound is, and this is how we do it. The more noise you can expose yourself to without freaking out, the better. My rule was that I would spend as little time in silence every day as humanly possible. The more time you spend in silence, the more you allow it to progress. I was so severe that I couldn't tolerate the low, barely audible whirr of the AC in my place. Now I am pretty much back to normal. If you have any questions, please ask me, I would love to help in any way I can.
