On past Friday,4 days ago, i was gargling tap water (i put a little amount of salt and gargle) and as i was having my head lean back some water dripped from the cavities tha communicate through our throats, mouth and nasal cavities to my nose and you know i had the feeling of a running nose but it was the little water that went to my nose from my throat while gargling. Since then i am so scared of the possibility to contract Naegleria Fawleri... Is there any danger from that? Also 2 days now i feel my head and eyes heavy from time to time and have a slight headache which sometimes is more like a migraine behind my eyes. Most of times when i drink a painkiller it goes away but today i woke up fine and during the day while i was at my work a headache kicked in, more like a heavy head and behind the eyes and i feel like i have chills from time to time like when you are tired. My anxiety levels are throught the roof, what do you suggest to do???? Is my fear logic and real? If i didnt had any symptoms like that i would think more logical but now i cant and i am very afraid. Please your answers will help me a lot
