How the fuck im supposed to wipe my ass so i dont stain my boxers whit shit later?
It looks like a stage 3 or 4 pressure ulcer that has been packed with guaze. The mirrored lesions around his cocyx suggest severe moisture related skin damage. Put bluntly, this old boy sat in his own piss and shit for a very long time and was unable to relieve the pressure caused by his seating surface. Wheelchair bound and neglected? Christ alone knows, but judging by the wound packing someone is looking after him now.
The white material to the right of the anus? I suspect that is what we call slough. Basically just the outcome of untreated infection. Could be fungus or a form of gangrene though. If you look just above his scotum you will see a folder cloth material. That is packing which means he has one hell of an ulcer there. Someone is trying to help him, but this needs a surgery consult to debride all the dead crap, sample for osteomylitis and try to close him up. I don't think he's going to make it, but I'm just the nurse. We will see what we can do.
