Skin doctors have discovered a condition they've named 'PlayStation palmar hidradenitis', which causes very painful sores on the palms of hands.
Researchers for the British Journal of Dermatology outlined the case of a 12-year-old girl admitted to hospital with the symptoms, as reported by the BBC.
She had developed red lumps more commonly found on the soles of feet and thought to be a by-product of heavy, sweaty physical activity, such as running.
But our lazy subject hadn't been doing any of that. She had, however, recently started playing a PlayStation game for several hours a day. The little trooper even continued to play after the sores manifested.
Eventually, after 10 days abstinence, her hands healed and she was given the all-clear.
"If you're worried about soreness on your hands when playing a games console, it might be sensible to give your hands a break from time to time, and don't play excessively if your hands are prone to sweating," advised Nina Goad from the British Association of Dermatologists.
The researchers concluded that 'PlayStation palmar hidradenitis' could be added to the list of physical symptoms caused by addiction to videogames. Acute tendonitis, dubbed Wiitis, is another.
