The veteran entertainer is on the mend.

Already besieged with foreclosure woes and a prescription lawsuit, Ed McMahon is now recovering from his third neck surgery, ET confirms.

The surgery went "very, very well," McMahon's publicist Howard Bragman tells us. 

Last month, Johnny Carson's longtime "Tonight Show" side kick appeared on "Larry King Live" wearing a neck brace. As we previously reported, he took a fall last year and suffered a broken neck, necessitating the ensuing three surgeries.
