I'm SOOO happy you found him!! Sounds like he may have crawled through some really tight spots. I think you've got a good plan, to let him relax a couple days (especially since he just ate a big meal) but then inspect him to make sure there are no open wounds that need tending. If it's just roughed up scales, that'll probably clear up after the next shed or two. After you've checked him over and made sure he doesn't have any wounds that need your attention, I would leave him completely alone for a week or so. He may need to re-acclimate to his enclosure...or at least de-stress from his adventures.
