Used the Hokuto Shinken Carpal Tunnel Attack on myself today. Whacked side of knuckle against desk, that dreadful place below the index finger's first knuckle along the bone in the web between forefinger and thumb. Now entire arm feels crippled.

(a good two hours later) Well, rubbing it down with menthol-something-or-other and applying the heat tip of the Wahl to it has helped immensely. I still can't hold anything much in it for very long, but at least it doesn't hurt to type.
