I am not an ENT or Audiologist, but I have had many patients who complain of ringing in the ears or hearing odd sounds as 62milestojoe mentioned. I usually take it into account and look at symptom behavior. Constant or Intermittent? Causal factors (loud noises, upon change of position, etc...) and Associated Factors (does it occur immediately before or after some other symptoms).
- If it is constant, I would refer the patient back to PCP or ENT for further work up.
- If it is intermittent and associated with Causal or Associated Factors I would track it just like any other symptom associated with those factors (providing all other test results are negative).
- If it is intermittent with no particular Causal or Associated Factors I tend to think it is a form of a neuro-physiological feedback loop. Could be neural outflow associated with some other Nerve inflammation/ immune response ie ME, Migraine, Fibromyalgia or some other undetermined underlying issue such as High BP, Cardiac, pulmonary or disease state. This I would consider as a centrally up-regulated response.
It is always something I have taken note of and considered in relationship to every other finding. It also sparks my alertness to unusual or potentially hidden causes and leads me to ask questions about fatigue, sleep, brain fog, heavy use of stimulants (lots of caffeine), gut problems, activity level and tolerance and/or unusual pain complaints.
Not that this answers your questions, but may give you a different perspective.
