Los Angeles Lakers star Steve Nash tells TMZ ... his back is pretty messed up, but he's putting serious pressure on himself to come back and play this season.
Nash was walking (gingerly) to his car at Gjelina restaurant in Venice, CA last night when we asked him about the injury that's been plaguing the 39-year-old.
"It's rough," Nash said ... "but I'm gonna keep pushing and try to get better."
Nash has already been to a famous back specialist earlier this week and was diagnosed with nerve root irritation. He's expected to miss at least 2 weeks, but if it doesn't get better, word is, Nash might hang 'em up for good.
