I have a guy who has injuries in a circle around his ankle, where prongs have dug in (I'd say the wounds could be 1/3 to 1/2 inch deep). He's basically been kept in a choke chain with sharpened prongs around his ankle. I checked some foot and ankle anatomy pages and I'm sure he'd have some muscle/tendon damage but I don't know specifically how that would affect mobility or if damage wound even be permanent. Would this prevent him from walking at all, if he's trying to get away once he's gotten loose, or could he muscle through it, do you think? I can handwave some of it, maybe, because he has healing abilities, but they're not instantaneous.
