( CNN ) -- Glenn Beck shared Monday a secret he 's kept from almost everyone for years : He 's been battling a serious and rare illness . `` It has baffled some of the best doctors in the world . It has frightened me and my family , as we did n't know what was happening , '' the conservative radio and TV host said on TheBlaze , a network he founded . Eventually , he learned what was wrong : he had a variety of ailments , including an autoimmune disorder and adrenal fatigue . Speaking through tears , the former Fox News host detailed the progression of his illness and the symptoms he suffered . Beck said he struggled to remember names , faces and conversations . At other times , his hands would shake and he would be forced to curl up into a ball . `` While I was at Fox , the pain would get so bad that my camera crew , our executive producer Tiffany and I , had worked out hand signals so they would know when to take the camera off of me , '' Beck said . `` We did n't know at the time what was causing me to feel as though , out of nowhere , my hands and feet , or arms and legs would feel like someone had just crushed them , set them on fire or pushed broken glass into them . '' Beck said he rarely slept , but was never tired . After taking a test for people with traumatic brain injury and testing in the bottom 10 % , Beck said he was told he would no longer be able to function in about five to 10 years . He went from doctor to doctor and tried different diets and medications , but nothing really worked . Beck began to search for his replacements . At the same time , he said , Beck and his wife continued to look for answers and found them at the Carrick Brain Centers , a rehabilitation center in Texas . `` We went and after a few short visits they found that I had several things going on -- from an autoimmune disorder to adrenal fatigue , and they found the connection on everything that was going on , '' Beck said . `` Me never having to sleep was finally understandable . The last sign of adrenal failure is a hyperextension of your adrenal glands . In other words , I did n't need sleep . I could have been lifting cars during my time at Fox ! '' After months of treatment and changing the way he eats , sleeps , works and lives -- along with hormone treatment and intensive physical therapy -- he believes he has reversed the process . `` My brain is back online in a big way , '' he said . `` I have received a clean bill of health . ''
