5 decades of beating things for a living with guitar players and loud Marshall amps has left me with a rather serious case of tinnitus (which I've always mispronounced as tin-night-tus rather than tin-a-tis).
I'm finally getting around to seeing the audiologists at the VA even though my primary care physician recently told me nothing can be done.
20 years ago they treated me with low dose Xanex and that seemed to help (although the VA eventually canned that Doctor as his 'better living through chemistry' philosophy seemed to involve Xanex for all his patients.
In order to get the hearing tests they're sending me for a "cleaning" which is a high-tech ear wax removal. I watched some videos of the procedure on u-tube out of curiosity. The videos are gross as the attachments they use gently suction and brush gobs of ear wax from deep within ear canals. It seems that using q-tips can actually force ear wax deeper and impact it into the ear drum and some of the recipients claim the wax removal helped with their tinnitus. I can only imagine what they'll find in these old ears, but I'm willing to try anything at this point.
