Sometimes when using a mouse, I feel uncomfortable with my little finger. How do we overcome this

You know, sometimes things that are taken for granted suddenly become uncomfortable when you notice something is not right. When using a mouse, my habit is to lift and bend my little finger, which means it doesn't touch the desktop or the mouse, but sometimes I feel it's getting in the way. If you are not used to using the mouse in other ways, I don't know how everyone feels?
