Candy Crush Saga, the popular game in smart phone left a man in California with an injured thumb.
The 29-year-old man played the game all day for 6 to 8 weeks, which lead to a tear in his thumb's tendon. He consulted a doctor after he felt that his thumb movement was constrained and reported that he did not have any pain.
The doctors said that it was surprising that the man didn't feel any pain and mentioned that video games may numb people's pain and contribute to video game addiction. The man claimed to play the game only between other things, as a secondary option and was not addicted to it.
Dr. Andrew Doan, a co-author of the case report, said that people need to be aware that certain video games could act like digital painkillers and make them feel runner's high.
