According to a population study performed in the Blue Mountains, 30% of people over the age of 55 years have some tinnitus. The problem is that there are structures within the brainstem that can perpetuate and amplify the tinnitus sound. These structures increase the tinnitus when you think about it or become anxious and stressed. Hopefully your tinnitus will subside gradually with the TRT treatment. There are many causes of dizziness and your normal MRI result excluded the more horrifying causes. The most common cause is

associated with a sudden drop in blood pressure, especially in people taking medications to lower their blood pressure, and is usually worse on suddenly standing up after lying down. Tinnitus can be associated with Meniere’s disease, a condition associated with too much fluid in the endolymph compartment of the inner ear. The dizziness or vertigo comes as attacks that last from 10 minutes to several hours and cause a sensation that the world is spinning around associated with nausea and usually vomiting. The attacks may be heralded by increased tinnitus in the affected ear and a feeling of fullness in the ear. If your dizziness has these characteristics, you should ask an ENT surgeon to investigate further. Another common cause of similar attacks of vertigo is migraine. Usually there is a past history of classic migraine or a strong family history. Often, some years after the last ‘headache’ migraine attack, the person begins to suffer attacks of vertigo due to changes in the blood flow through the vestibular nuclei (brainstem structures associated with balance). The attacks can be associated with tinnitus and a mild headache over the entire scalp. The hearing remains unaffected although some high frequency loss can occur in older age. An ENT surgeon or a neurologist can help establish the diagnosis and treat the problem.
