"The brain receives and sends signals to the body constantly. Nerve endings register the experience and the brain sends how to respond. If something is hot we move our hand away. When a limb is removed, the nerve ending is obviously gone. The brain on a functioning level doesn't know that and sends a pain or itch. That's weird but natural. It will go away with time." He rubs the bridge of his nose. That much is textbook. Hooray.

"They say massaging what you've got left and putting it under warm water helps. It could be over use of your knew kicker that's agitating the phantom itch. Visibly you can see and recognize that you're missing a leg, your brain is still slow on the uptake." Somewhere there's a pamphlet. He read it once before. Boring, useful information none the less. In fact, this would clear up so, so much. All the cleaning details and parts about sunshine are worth giving him, but to talk about all of it?

"As for the swimming, I'm sure there is something extra you can use that's lying around."
