Justin Bieber Visits Hospital for Wrist Injury Justin Bieber Visits Hospital for Wrist Injury

Justin Bieber's homecoming trip to Canada hit another snag ... in addition to being arrested, he had to hit up a local hospital on Wednesday for a wrist injury ... TMZ has learned.

We're told Bieber went to the Stratford General Hospital in Ontario to have his wrist checked out. According to our sources, it turns out he suffered a sprain.

As TMZ previously reported, Bieber was arrested Friday for assault and driving dangerously following an accident between Bieber's ATV and a pap in a minivan.

It's unclear if Bieber injured his wrist in the ATV accident ... or if he hurt it trying to reach something on a really high shelf. Ya know, cause he's tiny.
