#facial drooping

Hi friends, quick question. Anyone had facial weakness with migraines / headache? I CAN still smile normally if I try but basically my face feels weaker / droopier on one side. Second time it's happened recently. Can it just be teeth clenching causing migraines, causing this? Or maybe the clenching causing inflammation in turn pressing on facial nerves? No aura (none of my migraines as an adult have had aura), no confusion or slurred speech. Just an awful ache and my face is weakened and slightly drooping on one side.
