The left click of my mouse acts as right click and vice versa.

Sounds joke but when I left click my mouse/mouse pad it would act as right click and when I right click it would act as left click. Is somebody here has this problem.? I don't think that the mouse(device) is the problem because I tried other mice but still not fix.
