During the past week, I've been constantly switching between Guitar Hero 3, and PSU. Around last Saterday evening, I started to notice a sharp pain in my wrist and small finger almost as though they were going to break. During the time, I was attempting to play Cult of Personality on Hard, so I just assumed that the pain was a side-effect of hitting too many buttons during a short amount of time. But even after the song ended, the pain did not. This wasn't the first time that this had happened, so I did what I always did: flex my wrist a few times and get back to the game. Even after flexing for five minutes, my wrist refused to pop, and I heard my bones shifting the same way my knuckles do when they need to be popped. After an hour passed and the pain was still present, decided I'd take the problem to Dr.Google and see if anyone else had suffered the same problem. To my surprise I found an entire article on this wrist pain, and discovered that it even had a name: "guitar hero-itis".
