Los Angeles, Feb 1 : Actor Leonardo DiCaprio is still in pain from the back injury which he sustained while shooting "The Wolf of Wall Street".

The 39-year-old hurt his back in a scene where he falls down a stone staircase and is still in pain, reports contactmusic.com.

"He says he is in non-stop pain and has gained weight because he can't exercise. It hurts to lie down for too long and it's agony to twist his body into any crazy positions. Leo hasn't even been partying because dancing is painful," Star magazine quoted a source as saying.

DiCaprio has been nominated in the best actor in a leading role category at the 86th Academy Awards for his role as banker Jordan Belfort in "The Wolf Of Wall Street".
