Ear-Nose-Throat Problems

My son has tongue tie since birth, he is 9 months old now, I would like to know it's classified as internal or external congenital disease? Please clarify...

My son always says that his ears are itching. Consulted a doctor and he cleaned his ears and said his ears are fine. A few days after again he is complaining of an itchy ear and asks us to clean with earbuds. His ears looks clean after cleaning by the doctor and now no discharge nothing but still he asks to rub with earbuds. Please suggest remedies.

Sorry for asking again but I request humbly please alay my fear that if while drinking water I blew my nose accidently because there was a fly that sat on my nose, will blowing my nose while drinking water cause any water to go up the nose to cause N Fowleri infection? I was eating outside in a dhaba and so the water might not be that clean.

Since today morning i have mild shortness of breath.. i feel i am hyperventilating.. i went to doctor n he did my ecg and checked spo2 which was normal- 97%.. he told me to see ENT.. what ent problem can cause SOB? I do get itching all across my body sometimes n for that i take L HIST MONT on SOS.. 2 years back i had brain MRI which was normal for brain tissue but detected small maxillary polyps.. size was 16 x 9 mm

In my MRI report this is written BILATERAL SMALL MAXILLIARY POLYPS ARE SEEN LARGEST MEASURING 16 X 9 MM BILATERAL OSTIA ARE PATENT what does this imply?

Today my mother had boiled potatoes, but after boiling she washed it with non chlorinated water from the sink to cool them down instead of the RO water we use for cooking. As I was peeling the potatoes and mashing them to a fine paste, some droplets from the plate kept splashing in my nose throughout. Now I am worried that since the droplets kept splashing and I was breathing in and sometimes due to applying pressure breathing a bit heavily too and then later sneezed can the droplets get sucked up deep into the upper nasal passages or to the olfactory nerves and cause N Fowleri infection as it's summer?

I had consulted a couple of doctors and even after the high fees they hardly answer your queries and they were barely aware about N Fowleri infection risk. I am grateful to Doctors who clear my doubts here. Big thank you. Sorry for repeated queries, psychologist can't help as in past for panic attacks I had tried consulting one. Is it possible that if some dirty water or unchlorinated water drops fall into the mouth and nose while laughing and if we cough or gasp, inhale a bit deeply by mistake like in a sneeze or while trying to stop a cough, can we get infected if N Fowleri present in the water drops? Can one get infected while brushing teeth with unchlorinated water?

I have noticed enlarged lymp nodes under my jaw. However they aren't noticeable unless I put my finger and push it out. However one is slightly bigger than the other side . It is like a small crushed chetty size but is however tender and both are movable. Is this normal in me ?
