Hello,
Welcome to icliniq.com.
First of all, do not worry and do not go to some conclusion after an internet search. Now coming to your problem, Tinnitus is not a disease in itself but a mere symptom that is associated with varying number of diseases. By definition, it is a sound perceived for more than five minutes at a time in the absence of any external acoustical or electrical stimulus to ear. It may be subjective, when audible to patient only or objective when audible to both patient and examiner. Now exclude the objective tinnitus because if it was the case your doctor must have diagnosed it. Now come to subjective tinnitus. The causes may be as simple as impacted wax, middle ear fluid and eustachian tube dysfunction to more severe ones like Meniere's disease, otosclerosis, noise trauma or acoustic neuroma. Now let us try to exclude them first. Acoustic neuroma mostly is seen between 40 to 60 years, first symptoms to arise is progressive unilateral hearing loss associated with tinnitus after that comes other signs and symptoms like numbness of face, dysphagia and hoarseness in the later stage when the tumor becomes more than 2.5 cm. But you do not have a hearing impairment or other symptoms. For confirmation at least you can get a PTA (pure tone audiometry) and SISI (short increment sensitivity index). Now coming to otosclerosis which starts in the twenties but more common in females and presenting symptoms progressive bilateral (sometimes unilateral) hearing loss with tinnitus. Again for confirmation, you need a PTA. Now Meniere's disease, it presents with tinnitus, episodic vertigo, aural fullness and again fluctuating hearing loss, which is not present in your case. We have excluded the sever ones till now assuming you have written about all signs and symptoms and you don't have hearing loss, vertigo, aural fullness etc. If you have missed something contact me in my email. Sometimes, tinnitus is caused by very simple causes like impacted wax (which is not the obvious cause as your previous doctor must have diagnosed it) or eustachian tube dysfunction which many times gets unnoticed by the doctor. To rule out this at least you need to do Valsalva maneuver 30 to 40 times a day. If it is the cause, tinnitus gradually will decrease in severity. So, why not give it a try for two days minimum. If tinnitus is not subsiding after two days better to do some test like a PTA, tympanometry and a SISI. Hope this will help you and wishing you a faster recovery.
