I understand your concern.
Sorry for late reply.
As per your description,possible differential diagnosis of such fluttering sound in ear may include fluid accumulating in the middle ear, such as from an ear infection or inflammation or Eustachian tube dysfunction from sinusitis.
It can be due to spasm of a muscle in the inner ear.
This fluttering sound can also be a form of tinnitus caused by damage to the microscopic endings of the hearing nerve in the inner ear due to advanced age.
You need certain specific tests like an Audiogram,ABR or auditory brain response, acoustic reflex test or tympanogram and a clinical exam by an ENT specialist.
You should take OTC Otrivin nasal drops and nasal saline spray.
Also take OTC Advil for ear ache.
It also may help to try Eustachian tube exercises, such as forced yawning or chewing gum.
Feel free for further queries. It's good to discuss rather than quit.
