>>Nasty wound, that. Electrical discharge or mine?
Hard to say what caused it, isn’t it? Looks to me like it was festering for some time and I would think the blood flow to the wound, and therefore the effectiveness of antibiotics, would be substantially reduced. That would make it a more likely candidate for maggot therapy.
Some of those bugs don't mess around and the damage done in a couple of days can be phenomenal. Why anyone would ignore even the smallest wound is beyond me. Stuff I used to blow off as "just a scratch" gets tended to promptly, especially with the kids. (Hydrogen Peroxide is your friend!)
Still, if things go all to heck, knowing maggots can be your friend could be handy.
