A long-awaited study from the Centers for Disease Control on a mystery skin illness is finally done, and the results conclude that the odd sensations are all in the patients' minds.

FOX News Radio's Lisa Brady has details:

People who think they have what's known as Moregellons describe a horrifying ordeal that feels like bugs crawling on their body, sores oozing and fibers sprouting out of their skin.

But the CDC says its exhaustive, nearly $600,000 study, focusing on complaints in northern California, mirrors the previous conclusions of Mayo Clinic researchers: no physical cause explaining the symptoms, and most of the skin lesions were from the patients own scratching.

On psychological exams, the patients did show more depression than the general public, but the CDC says any further study is up to someone else.
