Same thing is happening to me. Not sure what's going on. Found a fix from an old wow forums topic from people that had the same problem (not sure if it's the exact same problem), which is to rightclick your wow.exe, go to compatibility, tick disable DPI, run in win8 compatibility mode, run as admin. Didn't fix it for me though but maybe you can try that.
My sensitivity also just randomly spikes in-game. Like when I constantly swing my camera from left to right for a few seconds, at some point sensitivity will jump up for like 1 second and then down again, it's really weird.
