Miley Cyrus hospitalized for an injury on her wrist

Miley Cyrus was hospitalized Friday night for what looks like some kind of weird flesh wound on her wrist ... and she quickly posted pics of the injury -- with a twist.

The 22 year-old singer snapped a photo in an L.A. ER, presumably of the wound but just like the rest of her Instagram photos she photoshopped a happy face.

She was hospitalized in Tarzana -- the San Fernando Valley -- and she was there Friday afternoon. course of her injury is unknown.

Miley also posted a pic of herself wearing the gown and noted how hipster it made her look. see pic after the cut..
