Kisame never truly paid his wounds any mind, especially when Samehada was still in his possession.
Devour his enemies' chakra to avoid exertion, shred away compromised flesh to cut off the flow of poison, wear the Shark Skin itself for a power boost -it didn't matter because he and the sword were almost the same and that meant it's scales would become his and he would walk out of battlefields practically unscathed.
Samehada was gone now, however, so this time the healing comes from medics, his own crude patchwork, or as it's the current case, Konan's own clammy hands washing the blood off his hair and pressing a clean tower against the torn skin of his scalp; he must still be somewhat concussed because he follows and leans against cool, smaller palms.
