Dr. Yasuf Yazici, an assistant professor of medicine at the NYU Hospital for Joint Diseases in New York City, was the senior author of a study that examined how often children experience pain after playing video games, theNews.com reports.
"The younger the kids, the more significant the pain," Yazici said. "The 7-year-old playing for two hours had more pain than the 10-year-old playing for two hours."
The professor added that it wasn't clear why younger children were more susceptible to joint pain through playing video games and suggested it may be because their muscles and tendons may still be in development.
Because of the increased risk of tendonitis and joint pain, it may also be beneficial for children with severe or life-threatening bacterial infections to avoid Levaquin. Recent lawsuits have accused the drug of causing spontaneous tendon ruptures as well as neurological side effects.
