On march 3rd i accidentally flushed my nasal passage with tap water. not knowing how bad it was, i began to panic in regards to pam. today is the 7th and i havent suffered any symptoms yet. how concerned should i be and should i got to the hospital?

In primary amebic meningoencephalitis (PAM), symptoms start 1 to 12 days (median 5 days) after swimming or having another nasal exposure to water containing Naegleria. Signs and symptoms of the infection include severe frontal headache, fever, nausea, vomiting, stiff neck, seizures, altered mental status, hallucinations, coma. It is a "rare disease" as defined by the U.S. Rare Disease Act of 2002

Not at all.
