Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you have ongoing abdominal symptoms, an unexplained recurring rash, or unexplained eosinophilia and have lived in or spent substantial time in an area where Strongyloides occurs.
Every sign above is quoted from the sofidex article on Strongyloidiasis. If you are not sure, err upward — it is always reasonable to be checked.
