Alright, so this started happening about a week ago. Whenever I try to play, my mouse randomly accelerates and shoots around. Other times, it's perfectly fine. It only happens in game. I cleaned my optical sensor (have cats, their fur can get stuck and mess with the sensor) as well as my mousepad just to make sure they weren't too dirty or anything. I've tried multiple different camera rotation speeds and none of that worked. I'm unsure where to go next.
