Hi there!
Count yourself lucky...if you want to call it that... My tinnitus is from nerve damage caused from years of loud equipment. I said earlier that mine was better after my surgery (acdf) but it is back now. Mine is so loud, that my high pitch hearing is at the bottom of the scale. That is why I wear 2 hearing aids. I got used to it, but it took about 3 years. Now it only bugs me when I let it. Stay out of caffeine, and msg and it might help.
Good Luck,
Dave
