JUSTIN CONTINUES HIS WORLD TOUR HES FEELING MUCH BETTER 🙌

The disease he was battling was called Ramsay Hunt Syndrome, which was virus-driven ... and caused facial paralysis, among other issues. Justin said he'd need time to recover.

Well, he's certainly done that of late ... soaking in some R&R with his wife, Hailey, by his side, no less. Looks like he's feeling up to singing again and, hopefully, Ramsay Hunt's in his rearview going forward. GLAD YOUR BETTER JUSTIN
