Fluid filled cyst removed from left side of face between eyebrow & temple 3 days ago. Why can't I move my left eyebrow? (Photo)

I'm 3 days post-op and I can't move my left eyebrow or the left side of my forehead I have feeling there but I just can't move them no matter how hard I try. There is very little bruising, swelling and it isn't hot/warm to the touch it is of course tender but, I'm more concerned with my face I have a 7 day post-op appointment with my Dr but I would really like some kind of information about why I'm not able to move just my left eyebrow and the left side of my forehead.
