In any game of D&D, 1e, or 2e I've ever played I don't remember heavy combat for more than one game day at a time. We'd spend a fair bit of time role-playing to wherever we were going, go full throttle to the dungeon/keep/cave/lair in one go and then role-play our way home.
Tracking out of combat healing never happened because the amount of time to the next combat day was always long enough in the future that time to heal was always hand-waved away.
