I was in an explosion involving 10,000 gallons of lpg on a construction site.
The explosion threw me about 30 feet,the impact trauma shattered my spine & a bunch of bones,couldnt move a muscle from the waist down..
Worst pain........crawling away from the fire while i could feel the flesh on my upper back cook,i could feel it all above waist,nah,thats 2nd worse.
I think the worst was waking up in the burn unit,strapped down while they peeled the seared skin from my body,nah even that isnt the worst.
Laying on a bare metal table under several 1,000 watt metal halide lights & baking to a crisp,after the dead skin & flesh was crisp they would work me over with scrub brushes to remove dead flesh,you scream until you pass out.
I can still smell my flesh cooking if i close my eyes & think back,its not something i do often.
