You seem to equate physical pain with deep anguish. This is just not the way terror works. Look at the way torturing by terrorist and the governments work (haha same thing? don't care).
True pain comes not from physical pain but from the fear of it, and from other things deep inside, memories, loss, fear, lack of control is the main thing.
To me I think the most terrifying thing is seeing yourself fall and become exactly what you despise and know you could be. There is nothing that can bring you back from that, and it's always there.
Wounds heal, aches go away, feelings and memories generally aren't so flighty.
