Not to get off topic, but reminds me of the great western movie "One Eyed Jacks" with Marlon Brando. The scene where his hand is tied to a hitching post and smashed with the butt of a Shotgun. Later he goes off in solitude to mend his hand. Ends up tying two fingers together and learns to shoot all over again.

I wish the OP luck. I think if there is a will there is a way. Just let pain be your guide.
