Phillip Phillips Hospitalized: 'American Idol' Contestant Rushed to Doctor for Emergency Medical Treatment

Phillip's dad tells TMZ ... his son has had 5 procedures to remove kidney stones. He says it's been a problem since October. As for performing, we're told Phillip is determined to continue on A.I. and will postpone any type of procedure ... at least until he knows the results tonight. But it's still really painful.


"American Idol" contestant Phillip Phillips was taken to a medical facility this morning for emergency treatment ... TMZ has learned -- and his future on the show is now in question.

Sources tell TMZ, Phillip -- the guy who always performs with a guitar on the show -- was complaining of intense pain in his abdomen ... and it seemed serious enough to sound the alarm.

The nature of the medical emergency is unclear -- but we're told people close to Phillip suspect it could be gallstones.

A source at the Georgia pawn shop where Phillip used to work tells TMZ, the singer was hospitalized back in January for a similar condition.
