Don't stress him out over it. IF he's sick, that level of stress could just make it worse. Just let him be...bump the temps a couple of degrees if you can...and watch him over the next few days. Watch for excessive yawning, propping his head up to sleep, mouth slightly open all or most of the time, wet streaks along the sides of the enclosure or furniture.
Won't hurt to skip a meal to allow his body a chance to rest. It's possible maybe he was just having a hard poo and was flexing his body a lot to push it all out?
