In Oddworld: Stranger's Wrath, you press a button that makes Stranger shake himself like a wet dog, expelling all the darts stuck in his body. How simply getting rid of the darts heals his wounds is a bit of a mystery.
Another thing that always seemed strange to me is how in HL2, Gordon can still walk around after a "major fracture". Either the HEV suit can instantly heal broken limbs, or the leggings act like a splint in the event of a fracture, allowing the user to walk without too much discomfort. Exactly how medpacks and health stations heal things like radiation poisoning is also beyond me. It must be that magic green juice.
