Thanks for all these additional information.
I understand your concern.
Well as you describe,he has developed ear infection and eustachian tube blockage due to persistent sinus infection/nasal septum perforation.
He needs to be seen by ENT specialist for a clinical examination rather than consider wait and watch approach.
His symptoms'll not improve without getting proper treatment.
He shouldn't ignore his symptoms.
Nodules under ears are swollen lymph glands and mandible pain indicates infection,Temporomandibular joint syndrome.
He should try some self care measures like
Do steam inhalation.
Try OTC Otrivin nasal drops.
OTC ear drops for pain relief can be tried.
Warm compresses around swollen lymph glands,mandible can be helpful.
He should elevate his head while sleeping.
Also take OTC Motrin and Claritin.
Start a multivitamin supplement.
