It’s everyone’s worst nightmare: food poisoning . . . on a plane!

Eighties heartthrob Corey Feldman had a medical emergency during a flight from Chicago to Los Angeles on Monday and was met by paramedics at the gate who rushed him to the hospital.

After spending the night and numerous tests to see if the tummy turbulence was pancreatitis or gallstones, his rep tells us it was just a good old fashioned case of food poisoning.

It is unclear if the “Goonies” star was a victim of airport food court dining.

“Corey is doing much better and is now out of the hospital,” the rep tells us.

A source close to Feldman told TMZ the ’80s teen star was feeling sick on the flight and was checked out by a fellow passenger who is a doctor.

“Corey wants to thank everyone for all of the love and well wishes,” his rep told us. “He has definitely seen a lot of the messages and really appreciates everything.”

Feldman is releasing a new single called “What Am I Here 4” on June 22nd and is celebrating his birthday with two performances in California the weekend of July 25th.

Feldman was in Chicago to attend an anniversary celebration for the 1986 classic “Stand By Me,” along with co-stars Jerry O’Connell and Wil Wheaton.

Their co-star River Phoenix died of a drug overdose on Halloween 1993 at just 23 years old.

Late Sunday night, Feldman shared a carousel of photos and videos to Instagram of him driving to Chicago for the event. He stopped by Michael Jackson’s childhood home in Gary, Indiana for an impromptu visit to “pay respects” to the late singer.

Jackson died at the age of 50 after suffering a heart attack caused by a drug overdose on June 25, 2009.

“We’re on our way to Chicago to tear it up,” Feldman, who competed on “Dancing With the Stars” last fall, said in a video on social media. “Gonna be a great night. Lots of people coming — thousands.”
