Prestigious medical journal the Lancet reported of a 34-year-old woman in Granada, Spain who complained of sore wrists, and was diagnosed with "WhatsAppitis" — named for the instant messaging service WhatsApp — after the doctor ruled out carpal tunnel syndrome and nerve damage.

The woman had spent at least six hours with her phone in her hands, exerting her thumbs to respond to messages.

The Lancet wrote about the diagnosis, explaining that the treatment consisted of non-steroidal anti-inflammatory drugs. Treatment also included "complete abstinence from using the phone to send messages."
