>>2952444In short, if you think necrosis is worth $10,000 to the system (that is, if, in absence of a health system, you personally losing 10 grand would on balance suck about as bad as getting and being treated for necrosis), and that in your personal "expertish" opinon you have less than a 1% chance of getting an infection, then maybe you can skip going to the doctor.
But if necrosis seems a suckier prospect than 10 grand (or if losing a limb seems suckier than 100 grand), or you don't have an estimate of the percentage, or 1% seems fair enough (I'd say 0.1% of my hangnails get infected, and that shit's tiny), then get your ass to the doc.
