>My Occupation has me in contact with Noise levels between 80 and 130
>db....I wear hearing protection in the higher range...ie ..engine room.
>I have been directly and indirectly exposed to a very filthy
>airconditioning unit and the chemical Hexane, an industrial degreaser.
>Phosphoric Acid...and Diesel oil....Paints containing solvents....and
>typical household cleaners and chemicals....
>Today the swelling is mainly in the cheek and temporal area and above a
>few inches....Occuring mostly in the morning ...decreasing by late
>afternoon...
>The disequilibrium continues as does the ringing and tingling, I have a
>hard time with memory and fine motor movements....I have had no pain,
>However am quite fatigued.

>negitive...CT'S...MRI's...X-ray's, Chest X-ray....blood tests checking
