I'm not relatively new to tinnitus, I've been dealing with this condition for over two years now with little hope, but I wanted to turn to the community for any ideas. My left sided tinnitus became prominent 2 years ago, and I chalked it up to years of loud music events, although the fact that it's only in one ear is unsettling. The main point I can make here, is that when I press firmly on the left mastoid section (the edgy bone area directly behind the ear and above the jaw), my tinnitus gets much MUCH louder, I'd say like 3-5x louder. So much so, that I cannot fall asleep resting my head on that side. Pressing the same on the right side has absolutely no effect. I've had CT scans and an MRI over the last 12 months for sinus issues (I had a balloon sinuplasty earlier this year with very positive results), but no one could ever make anything of the tinnitus. The only other thing that I could differentiate with left from right side is there is also a cyst on that left mastoid section, but my ENT had ensured me several times that that is common and unrelated. Any ideas what may be going on? Is there a specialist I could be following this through with?
