Does any of this apply?
Book an appointment
Routine follow-up may be appropriate after treatment to confirm that strength, balance, breathing, and swallowing have returned.
Arrange reassessment if recovery stops, symptoms return, or weakness remains after the expected recovery period.
The article also says
A tick bite without weakness is not usually an emergency.
Monitor for new symptoms and follow local advice about tick removal and tick-borne infections.
Every sign above is quoted from the sofidex article on Tick paralysis. If you are not sure, err upward — it is always reasonable to be checked.
