What you are describing sounds a lot like synkinesis where muscles that should not move together do. A classic example is a blink coupled with a rise in the corner of the mouth. This is due to nerve injury to the zygomatic branch and occurs when the nerve regrows but ends up controlling the wrong muscle. I should know since my surgeon damaged the zygomatic, buccal, and other branches of the facial nerve on both sides of my face and now have this permanent condition.
