TV's action hero Chuck Norris finally faced a villain he couldn't beat -- and it almost killed his wife.

According to Sunday's edition of Full Measure with Sharyl Attkisson, Gena Norris nearly died from complications after having MRIs several years ago.

In the report, Gena Norris said that the heavy metal gadolinium injected in her to enhance the MRI images lingered in her body for years and caused burning pain. Repeated tests were unable to locate the cause.

"I just heard that still small voice deep inside of me that said, Gena your body is dying. And I walked out of the bathroom and he just took one look at me and he knew; I'm about to lose my wife," said Gena Norris.

Chuck Norris told Attkisson, "I saw death in her eyes. I saw her dying and I said you know I've got to do something."

The problems began after she had three MRIs in one week to evaluate her rheumatoid arthritis.

"I was in the emergency room for like 5 or 6 nights in a row and the symptoms had continued to get worse and worse. And by the fourth, fifth, sixth night, the burning just kept traveling and I would go in and they'd say, well what's wrong with you? And I'm like I, I don't know. I don't feel good. And I'm just, I'm burning. All I can tell you is I'm burning all over. I feel like I have acid everywhere in my tissues, I'm just, I'm on fire," she said.

While the Food and Drug Administration said there is no evidence of poisoning, it is investigating reports of chronic pain and other symptoms to determine if "there are any potential adverse health effects," Attkisson reported.

For Chuck Norris, the feeling helplessness was horrible.

Chuck Norris: "Well it's the helpless feeling, you know cause I'm kind of a take charge guy, and then here I have something where I cannot do anything and it was, it was horrifying and, and uh, I just thank, thank God that we were able to weather it and that she did get better and I got my wife back."

The show airs Sunday on Sinclair stations nationwide, and is streamed live on Sundays at 9:30 a.m. at www.fullmeasure.news.
