AP PhotoTravis Barker may have been released from Georgia's Joseph M. Still Burn Center last month, but his ongoing treatment is far from over.
E! News has confirmed that the plane crash survivor is currently receiving care at the Grossman Burn Center in Sherman Oaks, Calif., and has undergone surgery since his arrival last week.
A source says the former Blink-182 drummer's condition has been "up and down" since his admittance.
The 32-year-old rocker was released Sept. 29 from the Augusta, Ga., hospital where he and Adam "DJ AM" Goldstein were taken in the immediate aftermath of the takeoff crash of a Learjet that left the other four people on board dead.
Barker suffered second- and third-degree burns in the Sept. 19 accident but, along with Goldstein, is expected to make a full recovery.
