Im a Navy Corpsman It doesnt sound like a brown recluse"real popular round these parts" necrosis would set in dying flesh around area. also the bite would turn into a deep hole and the puss would smell like ass.Speaking from experience.We get alot of Marines with recluse bites. Those are some mean lil fuckerz. You might wanna get that looked at like yesterday. unless you want one of those new carbonfiber prostetics?
