Unilateral tinnitus and pulsatile tinnitus?

Hello, doctor.
Two years ago, I experienced dizziness and a heavy head, which led me to consult a neurologist.
At that time, I was prescribed nerve repair agents and B vitamins, and after a while, I felt better.
I attributed my symptoms to autonomic nervous system dysfunction due to a general feeling of discomfort.
My college lifestyle has been irregular, with a habit of staying up late and waking up late, and my studies are mostly computer-related, which keeps me in front of a screen.
Recently, I have experienced dizziness and a heavy head again, accompanied by muscle soreness and fatigue.
During this time, I noticed tinnitus in my left ear, which I can hear at night.
I started taking B vitamins and eating fruits, along with going to bed earlier, and my dizziness improved by about 50%.
However, I still visited the same clinic from two years ago and mentioned the new onset of tinnitus.
The doctor believed it was caused by nerve tension and prescribed similar nutritional supplements (including B vitamins) and a mild central nervous system stabilizer.
While the dizziness has not been a major issue, the tinnitus in my left ear has worsened significantly, and I have mild headaches.
Loud sounds also make my left ear uncomfortable.
I notice the tinnitus during the day indoors, but it disappears on the street, which has worsened my sleep and caused anxiety due to high-frequency sounds.
Could this tinnitus be part of autonomic nervous system dysfunction? Since it is unilateral, should I get an immediate examination? Should I prioritize seeing an otolaryngologist or a neurologist? Thank you for your response.

Mr.
Pei, you mentioned: "However, the tinnitus in my left ear has worsened significantly, accompanied by mild headaches, and my left ear also feels uncomfortable when exposed to loud sounds." Unilateral tinnitus symptoms do not typically resemble those of autonomic nervous system disorders.
Generally, the autonomic nervous system is regulated by the sympathetic and parasympathetic nervous systems—one acts as the accelerator, while the other serves as the brake.
The sympathetic nervous system is responsible for stimulating the body, leading to increased heart rate, faster breathing, and increased sweating.
Once the activity ceases, the parasympathetic nervous system takes over, slowing the heart rate, reducing breathing speed, and decreasing sweat production.
You mentioned that the symptoms of tinnitus are more likely related to issues with the auditory nerve or the structures between the inner ear and the brainstem.
I recommend that you first consult an otolaryngologist to rule out any inner ear problems, and then, based on the ENT doctor's advice, consider seeing a neurologist for a brain examination.
Thank you for your inquiry, and feel free to discuss any related questions! Wishing you good health, peace, and joy.
Dr.

More Info

Unilateral tinnitus, or ringing in one ear, can indeed be related to autonomic nervous system (ANS) disorders, although it is essential to consider various factors that might contribute to this condition. The autonomic nervous system regulates involuntary bodily functions, including heart rate, digestion, and respiratory rate, and it can be influenced by stress, anxiety, and lifestyle factors such as irregular sleep patterns and prolonged computer use.

Your symptoms of dizziness, muscle soreness, and the onset of tinnitus following a period of irregular sleep and increased stress from academic demands suggest that your body may be responding to these stressors. The ANS can become dysregulated under stress, leading to symptoms such as dizziness, fatigue, and tinnitus. Tinnitus itself can be exacerbated by stress and anxiety, creating a cycle where the perception of sound becomes more pronounced during periods of heightened emotional distress.

The fact that you experienced relief from your symptoms after taking B vitamins and adjusting your sleep schedule indicates that lifestyle changes can have a positive impact on your overall well-being. However, the worsening of your unilateral tinnitus and the emergence of headaches and discomfort in response to loud sounds are concerning and warrant further investigation.

When considering whether to seek medical attention, it is advisable to consult an ear, nose, and throat (ENT) specialist first. An ENT can perform a thorough examination to rule out any underlying conditions that may be causing your unilateral tinnitus, such as ear infections, eustachian tube dysfunction, or even more serious conditions like acoustic neuroma. They may also conduct hearing tests to assess the extent of any hearing loss associated with the tinnitus.

If the ENT evaluation does not reveal any significant issues, or if they suspect that your symptoms may be related to an autonomic nervous system disorder, they may refer you to a neurologist for further assessment. A neurologist can evaluate for any neurological conditions that might be contributing to your symptoms and can provide treatment options that may include medication, physical therapy, or lifestyle modifications.

In the meantime, managing stress through relaxation techniques, regular sleep patterns, and a balanced diet can help alleviate some of the symptoms you are experiencing. Cognitive-behavioral therapy (CBT) may also be beneficial in addressing anxiety and stress-related symptoms, including tinnitus.

In summary, while unilateral tinnitus can be associated with autonomic nervous system disorders, it is crucial to undergo a comprehensive evaluation to determine the underlying cause. Starting with an ENT specialist is the best course of action, followed by a neurologist if necessary. Addressing lifestyle factors and managing stress can also play a significant role in improving your symptoms.
