I can't move my mouse horizontal[Garry's mod]

I can’t move my mouse horizontal
I was on a Murder server and while I was playing a screamer popped up on my screen and when I rejoined my controls where tampered with and my mouse could no longer move left or right. Only in game I can move it anywhere in menus but in game I can’t do the same. Anyone knows what’s wrong?

Do -config in your start up options run it once and then remove it, resets your entirely config. Should resolve it.

Don’t work…((
