I have Tinnitus that manifests itself as a high pitched noise. I cannot say what caused it but 2 things happened before it started.
1. I mistakenly took a high dose of aspirin. I read somewhere that can cause it.
2. I hit my head pretty hard. As a result of the hit which I believe caused a mild concussion, I experienced several things which not one doctor believed. I mention this because that caused me stress.
I mention the stress because recently I have noticed that if I am stressed, and who isn't lately, I realize that I am clenching my jaw. I also noticed that when I clench my jaw the Tinnitus gets louder. If I consciously relax my jaw, the Tinnitus gets quieter? Not right away but over time. There are lots of causes of Tinnitus and this may only work for me because of the cause of my Tinnitus but I thought I would just pass it on.
Interesting thing happened recently, I took a 5000IU vitamin D after dinner and the next morning my Tinnitus was barely noticeable? Could have been something else but...? I will continue to research...
Warning...taking 5000IU of vitamin D is not wise, The recommended amount is way, way lower. I don't remember what it is but...wow...it ain't 5000. I don't even know why they sell it. I had not checked but I figured if they have it on the shelf for sale it must be OK? Right? According to the info I found...that is a no, no!!!!!!!
