Nick Cannon Explains "Health Scare"

Nick Cannon is back to work, and spoke about what really happened on his show on 92.3NOW. Nick Cannon spoke about what his wife, “Mariah Carey” called “mild kidney function” on twitter.

"I'm one of those people who have always been this way ... I thought I was healthy," Cannon explained on his radio show Tuesday.

"I was trying to be Superman and I hadn't slept for maybe four days because I was taking care of the kids," he said, adding that everything just snowballed from there.

"Two days before New Year's, I started to feel this horrible pain in my back," he said, and figured he maybe hurt himself while working out.

Mariah Carey called the doctor after she found her husband lying on the floor with severe back pain. At first doctors thought it was kidney stones or an infection.

"They did some more tests ... and -- it took a day or two -- and they were like, 'We think it's a little more serious than a kidney infection. We're going to keep you in the hospital. You need to stay here.'"

They came and told me that my kidneys aren't functioning. Not just one -- not the one that was in pain -- both both of them weren't functioning right," he said, later explaining what happened. "My immune system started to attack my kidneys ... And my kidneys pretty much failed."

Cannon's condition improved and he was sent him home after being transferred to an L.A. hospital. However, he ended up heading back to the hospital after his kidney pain returned.

Now hes is back, saying he is recovered and is going to start 2012 with a bang, like he intended too.

All the best Nick
