I have had a inner ear problem for years and at one time had an ET tube placed which help me a lot. With plugged ears, your eustachian tubes — the pathways between your middle ears and the back of your nose — become obstructed.
Ventilation tubes, in some cases, to drain fluid are place in a minor surgical procedure.
Vertigo or dizziness is a symptom, not a disease. Mental stress can make many forms of vertigo worse, but will not, by itself, produce vertigo.
I am not a Doctor so the information above is strictly FYI. I do feel you should visit your physician as many other things besides anxiety can cause your symptoms. I know how disturbed you must be feeling over all these physical problems so do advocate for yourself. Take care and let us hear from you how you are doing.
Kindly,
Kitt
