SaullixThespikedballofdoomHave any pro esport players truly suffered an injury directly caused by Gaming™?
Yes, especially wrist and other hand injuries. The SSBM scene had one of the top players in the world, Hax, drop out from competition due to wrist injuries caused the gamecube controller as one of the major contributing factors. He has come back to competition recently using a new box controller similar to hitbox fightsticks used in the FGC. I also live with a CSS surfer, Beetle179, who also has dropped off somewhat due to wrist issues caused by excessive use of his mouse. It's definitely something that exists.
If we're talking about surfers, I believe one of the top speedrunners in G-Mod bhop had to step aside for a while due to Carpal Tunnel Syndrome.
This is actually a huge thing in esports. Stretching and ergonomics are very important for playing fulltime games.
