Pat Sajak opens up about his emergency surgery. The pain was so …

(CNN) A month after “Wheel of Fortune” host Pat Sajak underwent emergency surgery for a blocked intestine, he is sharing all the painful details.

In his first interview since the operation, Sajak told “Good Morning America” that in the moments before the surgery, he thought he was going to die.

The game show host said he started to experience “excruciating” pain while on a morning walk with his daughter in November.

Hours later, he was doubled over in pain, preparing to enter surgery.

Then, he said, his doctors gave him a drug that swept the pain from his mind.
