this is what your arm looks like after a surgeon performs a fasciotomy following a snake bite.
I obviously don't know the medical particulars of this case, but way too many unnecessary fasciotomies are performed following venomous snake bite, according to the most experieced surgeons (someplace in AZ I forget) in this specialty.
Copperheads can be nasty too, tho there is not a single confirmed case of a copperhead bite directly killing someone.
I remember once, in my youth, hunting for grey-banded kingsnakes near Big Bend Texas and met some blokes from the UK who wanted a pair of Western Diamondbacks to take home and breed.
My buddy (now perfesser at SWTS) promised fellow we'd save a female Western Diamondback for him. To sex the animal, you gotta carefully insert probe into urogenital vent of snake while your very trustworthy and steady buddy holds the rattler upsidedown! (I only assisted in a few) The first 16 rattlers we found on road were dudes cruising for babes. Had to sex frikkin' 17 rattlers before we found a female!
