Re: hand rash
I had a similar skin condition many years ago.
My son drove his 4x4 truck through an open cesspool.
Thinking it was a pond of water.
The shock must have been teeeeemendous!
When he tells of the screaming passengers in the bed of the truck.
He had the stereo and the ac on high when he hit the puddle of liquid.
He thought they were having fun and screaming for more.
He went through the puddle many times.
They were screaming all right "It's not mud It's not mud".
He even washed it with clorox and a pressure washer.
Several weeks later I worked on the truck I got the rash you describe on my hands.
It lasted a long time over four months ,until I realized I needed an antibiotic.
We finally got rid of the truck.
I would not discount the radioactive Chinese aluminum.
Ir has happened before with radioactive Mexican rebar.
