The symptom of the disease you are suffering from is- subjective tinnitus without so far identifiable cause, rather even after through search no cause can be found out and practically saying it is very difficult to treat most of the cases rather main therapy is adaptation..and with or without retraining therapy.But I am telling as if representing a mug of water from a sea only.So I would suggest you to consult any good ENT clinician for evaluation first before taking my note that it won't be cured .Stay positive.
