Be seen today
Contact a healthcare professional promptly if you develop fever, severe tiredness, headache, or muscle aches after a tick bite or after spending time in a western mountain area.
Do not wait for a rash, since mountain fever often causes no rash.
Seek urgent same-day care if you have:
Repeated vomiting or difficulty keeping fluids down
Very little urine, faintness, or other signs of dehydration
Worsening headache, unusual bruising, or bleeding
Fever that is persistent, returns, or is getting worse
Symptoms that improve and then become significantly worse
And for anyone, someone who:
has a fever with a stiff neck, a rash that does not fade under pressure, or severe headache
Every sign above is quoted from the sofidex article on Mountain fever. If you are not sure, err upward — it is always reasonable to be checked.
