Is any of this happening?
Be seen today
Seek prompt medical advice for new blurred vision, floating spots, eye pain, or reduced vision.
Eye inflammation needs timely examination because several conditions can produce similar symptoms.
Seek urgent medical care for chest pain, worsening shortness of breath, marked weakness, or difficulty walking.

Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you have ongoing fever, cough, wheezing, abdominal pain, unusual tiredness, or an unexplained high eosinophil count, especially after significant contact with soil or animal feces.
These symptoms have many possible causes, so an assessment is needed rather than assuming they are due to a parasite.
Every sign above is quoted from the sofidex article on Visceral larva migrans. If you are not sure, err upward — it is always reasonable to be checked.
