Thank you for all the information,
Involuntary jaw movement can be possible.
Anxiety, stress can cause it.
Hyperkinetic movement disorder can produce such symptoms.
You may need to take a referral for a neurologist.
OTC medicine would not help.
EMG, scan and other tests can be needed.
As you are seeing doctor tomorrow, after preliminary examination, doctor can decide on referral.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
