Am I blue?

Well, yes.

Paul Karason puts a whole new spin on "feeling blue." For more than a decade, the 57-year-old has been living with a blue face.

Fourteen years ago, Karason developed a bad case of dermatitis, which results in swollen, reddened and itchy skin. He started self-medicating, using a treatment called colloidal silver, which is made by extracting silver from metal.

Often touted by manufacturers as a cure-all, colloidal silver usually is found in a liquid form. Looking for relief, Karason drank the concoction and rubbed it on his skin — something the U.S. Food and Drug Administration does not recommend.

His skin slowly turned blue. [source]
