Dear Kelly, I had a case of Bells Palzy a few years ago. It was brought on by...what else...anxiety and stress..my biggest trigger. Facial numbness was my very first symptom of the lousy disease, years before my actual DX.
I hate to bring this up, but, please have the tests for a small Stroke/TIA. It is always a possibility and shouldn't be dismissed.
Call your Neuro, ASAP, and tell him/her your concerns.....er.....my concerns..
Thinking of You..
