Repeating the treatment with his injured shoulder, she touched him right at the tenderest spot.  There was a sharp lance of agony when her hoof touched the bandage, followed by a mild relief.  It still hurt, but the constant throbbing had been replaced with a duller, more-distant pain.  Dale wasn’t sure what to make of it—it seemed like she’d done nothing at all, yet he felt a little bit better.  Maybe she was carrying some kind of medical tricorder—like the one Dr. McCoy had—that somehow eased pain.  Carrying on the bottom of her hoof.  Which she’d walked on to get into the hospital room.
