I have pain and Tightness in ear.

I'm suffering from ear problem for more than 3 years after a trauma on the left side of my face. I have constant Tightness and uneasiness and slight pain in both of my ears and whenever i swallow i hear a crackling sound inside ear. I can pop my ear and during valsalva i hear crackling sound. Whenever i inhale deeply my ear gets clogged for some seconds. I have been to 12 different ENTs so far, everyone said i have eustachian tube dysfunction and gave me anti-allergents and steroid nasal spray and adviced to do steam inhalation 2 times a day. Nothing has improved my symptom. My CT PNS shows slight DNS and Inferior turbinate hypertrophy. The last ENT said that doing septoplasty and turbinate reduction surgery will alleviate all my symptoms. Another thing is i have jaw clenching habit and slight jaw pain. Visited a dentist recently and she performed CBCT-TMJ and CBCT airway scan and said i have TMJ disorder and probably all my ear problem is related to my TMJ. I'm absolutely clueless.
