Dizziness and Right-Sided Numbness: Possible Causes and Solutions

Dizziness and numbness on the right side of the body?

I have been experiencing dizziness and numbness on the right side of my body for the past four years.
The dizziness recurs after a while; it doesn't feel like the room is spinning, but rather a sense of terror, accompanied by numbness on the right side and a heavy weakness in my legs.
Each episode lasts only a few seconds, but it can occur multiple times a day, regardless of my position.
Sometimes I wake up dizzy while sleeping, and during these episodes, my vision and hearing are not affected.
I have previously consulted a neurologist and undergone tests, but the results were normal, and the cause remains unidentified.

Dr. Zheng Jueyi reply Otolaryngology

Hello, the symptoms are less indicative of an inner ear disorder and are more suggestive of central or vascular causes of dizziness.
If episodes occur frequently, it is advisable to continue evaluations with a neurologist.
Wishing you safety and health.

More Info

Dizziness and right-sided numbness can be concerning symptoms, especially when they have persisted for several years. Based on your description, it seems that you experience episodes of dizziness accompanied by numbness and heaviness on the right side of your body. These episodes can be distressing, particularly if they occur frequently throughout the day and disrupt your daily activities.

Given that you've already consulted a neurologist and undergone tests that returned normal results, it’s important to consider several potential causes for your symptoms. Here are some possibilities:
1. Vestibular Disorders: Dizziness can often be related to issues with the inner ear, which plays a crucial role in balance. Conditions such as benign paroxysmal positional vertigo (BPPV) can cause episodes of dizziness triggered by changes in head position. Although you mentioned that your dizziness does not feel like the room is spinning, it could still be worth exploring vestibular rehabilitation therapy, which can help improve balance and reduce dizziness.

2. Migraines: Some individuals experience migraine-associated vertigo or vestibular migraines, which can cause dizziness without the typical headache. These episodes can also be accompanied by sensory changes, such as numbness. If you have a history of migraines, this could be a potential explanation.

3. Anxiety and Panic Disorders: The sensation of dizziness and feelings of terror can sometimes be linked to anxiety or panic attacks. If you find that your symptoms are exacerbated by stress or anxiety, it may be beneficial to explore this avenue with a mental health professional.

4. Cervical Spine Issues: Problems in the cervical spine, such as herniated discs or degenerative changes, can sometimes lead to dizziness and neurological symptoms, including numbness. If you have not had imaging studies of your cervical spine, it might be worth discussing with your healthcare provider.

5. Peripheral Neuropathy: Conditions that affect the peripheral nerves can lead to numbness and weakness. Diabetes, vitamin deficiencies, and certain autoimmune diseases can cause peripheral neuropathy. If you have risk factors for these conditions, further evaluation may be warranted.

6. Transient Ischemic Attacks (TIAs): Although less common, TIAs can present with sudden dizziness and numbness. These are temporary episodes caused by reduced blood flow to the brain. If you experience any additional symptoms such as weakness, difficulty speaking, or severe headache, it is crucial to seek immediate medical attention.

7. Multiple Sclerosis (MS): While you mentioned that previous neurological evaluations were normal, MS can sometimes present with transient neurological symptoms. If your symptoms change or worsen, it may be worth revisiting this possibility with your healthcare provider.

In terms of management, here are some suggestions:
- Keep a Symptom Diary: Documenting when your symptoms occur, their duration, and any associated factors (like stress, diet, or activity level) can help your healthcare provider identify patterns and potential triggers.

- Physical Therapy: If vestibular issues or cervical spine problems are suspected, physical therapy may help improve your symptoms through targeted exercises.

- Medication: Depending on the underlying cause, medications may be prescribed to help manage symptoms, whether they are related to migraines, anxiety, or other conditions.

- Lifestyle Modifications: Staying hydrated, managing stress, and ensuring a balanced diet can help improve overall health and potentially reduce the frequency of your symptoms.

Since your symptoms have persisted for a significant period, it may be beneficial to seek a second opinion or further evaluation from a specialist, such as a neurologist or an ear, nose, and throat (ENT) specialist, who can provide additional insights and management options tailored to your specific situation.
