What he'd like is some cocaine, but he isn't going to ask for that, and even he recognizes that may not be the best idea. He does hurt, though, and he purses his lips, considering.

"And some paracetamol?" he asks, and he braces himself as a spasm of pain runs up his leg to his hip and across his pelvis. His head throbs again, and he doesn't really want Watson to get up at all, even if he would really like some pain medicine. This infection, he finds, and his absolute faith that Watson will get him through this, is helping him to get over the escaped criminal and the fact he got stabbed in the first place. It's a sufficient enough distraction, or at least it does a good job of scrambling his thoughts.
