"You can't fix me up if you're crying anyway, byon!" Ken contests hotly, even though he's feeling woozy already. Whether it's blood loss or exhaustion or starvation or pain or some hideous cocktail of them all, it doesn't really matter. He's not in a good state, and Chikusa will see he's pale. In fact, when Chikusa tears himself free, Ken falls back down with nothing to hold onto.

Ken's never cared about himself nearly as much as he's cared about the few people who mean anything to him. Seeing Chikusa's distress means that's all he can think about.
