So here's the scenario: Kieron, human cast member, gets between an ally and a minor demon and tries to fight the thing off on his own, like a 22-year-old given the excuse to play hero does. Kieron is absolutely huge (size and build of a professional strongman; closer to seven feet than six, four bills and change, muscular but well-upholstered); the demon is comparable to a very small bear or very large dog (maybe around 200#), but disproportionately powerful and armed with a set of nasty claws.
Long story short: Kieron slugs the demon; the demon recovers, takes a swipe at him, and lands a glancing blow to his ribcage. He's knocked down, the heel of its paw bruises his ribs, and it lacerates his side with its claws almost accidentally, leaving him with three or four approximately five-inch cuts at very least into if not through his subcutaneous fat (but not deep enough to jank up his obliques or worse; from a narrative perspective, this is more of a wake-up call than intended to be life-threatening). Between bruised ribs, carved-up love handle, and shock: what kind of medical treatment (stitches, hospital stay, recovery) is he looking at?
