I have similar to carpal tunnel symptoms from too much FPS on PC. Stopped playing FPS is 2009, still can't do a 30 min sesh without pain. I use controller for all games now. Started having similar issues recently, and got some acupuncture. It was applied for to my neck area, and it seemed to be from tension in my shoulders. Crazy how far the pain was from the root cause. Hopefully this helps someone reading this.
