Hi, thanks for replying. It seems that the jarring motion of driving on an uneven surface shook up my tinnitus. It happens if I bang my head accidentally as well or other such head trauma...
I researched the side effects of Pepsi and aspercreme, and both have tinnitus as a side effect over long term use. I believe these products contain the same substance as aspirin, which can also cause tinnitus. My general doctor and ENT originally told me not to worry, and that after a few weeks, it would go away. Well, 14 months later there is no improvement...
