It is impossible to speculate further on the evaluations of 3 ENTs. Presumably, the tests have ruled out what is usually considered serious disease, such as herpes zoster infection and a variety of tumors that can occur in proximity to the ear, at the base of the skull. If there truly is no evidence of fluid or other physical abnormalities, neuralgia or neuritis might be worthy of consideration. The trigeminal nerve is notorious for causing facial pain and muscle spasm, but it is conceivable that inflammation or other involvement of some small branches of this nerve or others adjacent to it could give rise to the peculiar sensations you describe. You might want to give consideration to having a neurologist evaluate your condition. The dizziness and "feel off balance" suggest a vestibular disturbance, which is the part of the ear concerned with balance.
You have had a CT scan but an MRI might reveal an abnormality, not evident on CT.
