Glenn Beck is revealing to the public the extent of his health problems.

On Monday, November 10, while speaking to TheBlaze TV, the former Fox News host opened up about his illness. While most knew that Beck had been having some health issues, no one knew just how extreme they had become.

“It has baffled some of the best doctors in the world,” Beck told the network he founded in 2011. “It has frightened me and my family, as we didn’t know what was happening.”

Beck described some of his symptoms that threatened to keep him from working. He said he had trouble with vocal cord paralysis, memory loss, eyesight problems, intense pain, and seizures.

“I was told by doctors just this last spring … that I could no longer work the way I had been working because it was literally killing me,” he said.

“While I was at Fox, the pain would get so bad that my camera crew (God bless them), my executive producer Tiffany and our director, Sarah, worked out hand signals so they would know when to take the camera off me,” Beck explained. “We didn’t know at the time what was causing me to feel as though, out of nowhere, my hands or feet, or arms and legs, would feel like someone had just crushed them, or set them on fire or pushed broken glass into them.”

After undergoing countless tests, Beck and his family moved from New York to Texas where he sought help at a local rehab facility called Carrick Brain Centers. That is where Beck finally received his diagnosis: an autoimmune disorder, adrenal fatigue, and Addison’s disease.

Beck had to completely change his way of life, but is now recovering from the debilitating symptoms. “After months of treatment and completely changing the way I eat, sleep, work and live, along with ongoing hormone treatment and intensive physical therapy, I have reversed the process,” he said. “Some of the physical scars will be with me for the rest of my life … but my brain is back online in a big way.”
