Tinnitus can be due to nerve damage. Those little hairs in there are fragile.
There are a couple things (alternative medicine) that you can try, I have personal knowledge that the first works.
An ayurveidic compound called triphala - it's three fruits, dried and powdered. I have seen it work on people with chronic Lyme disease which causes intense pain due to nerve damage as one of its many symptoms. I have also seen it work on chemo induced peripheral neuropathy.
The other thing I personally have not seen work, but which has good words on its efficacy - CBD oil. It's worth a try. Recommend Charlotte's Web, not just any old off of Amazon hemp oil.
