Flair, 70, was initially taken to the emergency room to be treated according to TMZ Sports.
They claim that their situation is "very serious", as Flair was in Atlanta when he became ill.
It's been two years after Flair has been put into a medically induced coma for 11 days after his intestine broke.
The legend of the WWE had a great bash for its stars on its 70th birthday in February and overcame this issue.
The Flair or WWE camp still have to comment on Flair's health, but fans have been slow to send their wishes.
One published: "The crossed fingers are fine"
Another added: "Prayers for The Nature Boy, luckily it goes out to 2.9999".
A third party wrote: "Pulling for you Nature Boy"
And a WWE companion commented: "Pray for your Rico"
A fifth wrote: "I ask for @RicFlairNatrBoy, a pure and absolute legend"
With another one added: "Two and a half years ago at Nature Boy."
Flair is officially recognized by WWE as world champion 16 times and joined the Hal of Fame of the WWE in 2008.
He kept his team career when he helped defeat Triple H Batista at WrestleMania 35.
