Does the flesh on the side of your face bubble and melt whenever you take a call? You might have contact dermatitis triggered by nickel, a common component in cell phones' casing. From Reuters:
"It is worth doctors bearing this condition in mind if they see a patient with a rash on the cheek or ear that cannot otherwise be explained," it [the British Association of Dermatologists] said. ... Many doctors were unaware mobile phones could cause the condition.
Safety concerns over mobile phones has grown as more people rely on them for everyday communication, although the evidence to date has given the technology a clean bill of health when it comes to serious conditions like brain cancer.
Nickel is present in 10 of 22 popular handsets, Reuters reports, but it doesn't chance to name them. As a result of this report, BBG recommends that you immediately stop eating cell phones until the Chinese government takes action.
