"I can't move my eyebrow," Bieber says in the Viddy video. "It's the weirdest thing, some weird stuff going on."
He adds: "I got into a fight with a glass window."
Earlier this week, Bieber almost caused a state of emergency to be declared in Norway after his fans swarmed the opera house where he was due to perform.
The singer's label Universal Music has since said that it regretted giving a free show.
At least 78 people were injured during the chaos in Norway.
