You are choking, cannot breathe normally, or your lips turn blue

Is any of this happening?
Be seen today
Seek prompt medical advice if the movements are rapidly worsening, causing mouth injuries, interfering with speech, or making it difficult to eat or drink.
New painful jaw, eye, or neck spasms soon after starting or increasing a medicine may be an acute dystonic reaction and should be assessed urgently.
And for anyone, someone who:
has a wound that is hot, spreading red, or leaking pus

Does any of this apply?
Book an appointment
Arrange a routine appointment if you develop repeated mouth, tongue, jaw, or facial movements, especially if you take or previously took an antipsychotic or a dopamine-blocking nausea medicine.
An early review helps document the movement and consider possible causes.
And for anyone, someone who:
has noticed a lump, a mole that has changed, or unexplained weight loss
Every sign above is quoted from the sofidex article on Oral-facial dyskinesia. If you are not sure, err upward — it is always reasonable to be checked.
