Navydad I have to wonder if your having been an electrician and probably gotten zapped many times has contributed to your situation. In a former life I did biological work with venomous organisms and way too many exposures to neurotoxins probably didn't help my current situation either.
I did get hit once with 480 Volts, it literally blew up the screw driver I was holding, it was on a system that we were not allowed to shut down, and it was my own fault,, I wasent watching where the screwdriver was, and grounded it out,,,,, talk about flashes and hot metal splasing all over your goggles,, but your not a electrician if you havent been rapped a few times,,, who knows,, before they did electrical upgrades thoughout the site, it was a electrical nightmare, the place was full of asbestoes too,, we would lift a ceiling tile out to work on something and the stuff was just laying all over the place,, of course we complained,, nothing was done,, we got a union,, and then they tok over and demanded it be removed, oh,, this was a Federal Govt. facility,,
