Don't know if you have seen them, but YouTube has videos showing hook removal.
One guy shows these graphic images in video, in which a guy imbeds something like 3, 2/0 Circle Hooks in his forearm, with barbs intact.
Then he shows the 3 ways of removing an embedded hook.
The man seems to use no anasthetic whatsoever, and seems to just ignore the physical pain.
I am glad of one thing in light of this subject. I have started crushing the barb on every fly that I tie.
