eustachian tube blocked (Sinus Infection)

Hi,

I have been suffering from eustachian tube blockage for a while now, it is on the right ear,

Symptoms:

I have white lines inside of my cheeks - white coated tounge & right ear tube blocked, have brain fog, impaired thinking, dizziness, always tired & sleepy.

I have tried following remedies

1) Nasal spray both non steriod & steriods (didnt work)

2) Neti pot with neil meds rinse - been trying this for few weeks its not of much help

3) have done liver flush, in the process of doing one more flush as i type

4) few drops on warm olive oil with cloves & garlic in it, started this from yesterday (dont see any progress either)

NOTE: i was a heavy smoker i have quit smoking only two days ago.

any help is highly appreciated
