Anything is possible but I think it is unlikely that they would "blow" like a spurting blood vessel you see in movies. More likely he'll gradually get progression of his disease and eventually nonhealing ulcers.
Yuk.
You're probably right, but I once used one of those old-school Schering Primobolan Redijects to stick in someone's thigh - the ones where the pin was like a knitting needle - and that must have hit a blood vessel as when it came out there was a proper jet of blood
And on a vaguely related note, some time back I scratched my balls a bit too aggressively while in the bathroom. When I looked down the blood was indeed spurting a fair distance away from me - couple of feet maybe - quite startling TBH
So we can but hope for a similar dramatic incident from Walker
