Dr. Conrad Murray Moves into Bigger Cell -- Still Complaining

The L.A. County Sheriff has moved Dr. Conrad Murray into a larger cell -- but the good doc still ain't happy with the upgrade, telling his lawyer, "I'm dying. You gotta save me."

Murray was transferred from a 5'x7' cell to a 8'x10' cell yesterday -- the biggest in the jail -- but he spoke to his lawyer soon after, saying, "I am a condemned prisoner right now. I look in the mirror and I don't even know who I'm looking at."

As we reported, Murray -- who is 6'5" -- has been griping constantly about his living conditions behind bars, claiming he's dying a slow death due to the cramped spaces.

Murray says the new cell doesn't have bars to elevate his leg -- which has become swollen due to a lack of movement. He says the new cell is also more isolated, and he still isn't getting more exercise.

We're told Murray is grateful for the attention -- but it's just not enough.
