I am sorry I trouble you kind Doctors with questions about same disease. The fear if this disease and the fact that I haven't done anything worthwhile in my life makes me more scared. 2 Questions: one if while eating outside me and my friend were talking when his spit shot up way up in my nose while speaking loudly as there was music there. Since the salad we were eating & water we were drinking may not be chlorinated as from hand pump. Second while washing hair some water went in my right nostril, I didn't feel pain or stuffiness in nose afterwards  and I blew my nose on fear for like 5 mins. Can in any of the above scenarios whether the spit droplets or the water go far up in my nasal passages and near the olfactory nerves to cause an N Fowleri amoeba infection? I know it's far fetched but I am very concerned.
