I'm wondering if I could have meningitis about 13 days ago I used ice in my nose to alleviate some pain and inflamation...This evening I started feeling nauseous and dizzy...What are the odds I've been exposed to nagleria fowleri and could these be early

Very rare. Between 1962 & 2016 there have only been 7 case-reports of Primary Amebic Meningoencephalitis caused by Naegleria fowleri. If the ice was made from municiple water system - the odd are exceedingly low.
If . If you are having headache, fever, vomiting, neck pain or stiffness, or any rash, you should be evaluated for possible meningitis. If you have those symptoms then you should go in immediately for a complete evaluation.
