Book an appointment
Arrange routine medical care if symptoms are mild but are not improving, keep returning, or follow a new medicine.
Recurrent swelling without an obvious infection should also be assessed.
Every sign above is quoted from the sofidex article on Uvulitis. If you are not sure, err upward — it is always reasonable to be checked.
