a non-exhaustive list of what he's got going on medically (head issues only)
ear has fallen off. that thing is just blisters by the end of the movie, and with the messed up jaw situation, it just rotted right off;
related, his vestibular system is all wonky. had a few weeks of BPPV which then later had to be medically corrected;
left side hearing is pretty shot now;
teeth aren't rooted in bone (except maybe two) but in facial muscles and skin tissue, so they are very loose and fall off constantly. don't worry, the fuckers grow back fast;
teeth roots are also knotted up in the facial neves, so most of his left side is deadened. can express a bit but not much, sometimes it hurts. can make teeth fall off faster;
because of above, his left eyelids don't respond properly. has to use an eye bandage to keep the eye closed so it doesn't dry out;
can still see through it even when closed, and he wishes he didn't, those visions are nightmarish;
so many sinus complications, constantly getting clogged noises, ear popping (which hurts like a motherfucker) and inflammations;
vocal chords messed up by the mutations, even after corrective surgery his voice cracks or sometimes fully doesn't work at times. shouting and high notes almost impossible;
again, constant drooling and dry mouth issues. can only eat with assistance of bandages over his face to keep the teeth somewhat closed;
lots of issues with his original set of teeth as well, had to have a few molars replaced;
facial lymph nodes issues, has to do drainage massages daily;
hair loss and thinning for a while, never quite fully recovered original density;
bouts of visual agnosia and photosensitivity due to mutations reaching his optic nerve and frontal lobe, and the concussion really didn't help;
skin grafts on the way, but they are often rejected. injuries refuse to dry out though, so gotta keep on trying.
