Experiencing Unexplained Sensations of Motion: Possible Neurological Causes - Neurology

Share to:

It feels like there are aftershocks, but my body is not moving?


Hello, doctor.
Recently, I have been experiencing a sensation of swaying, similar to being on a boat.
This occurs whether I am sitting, lying down, or walking, but my body feels normal.
The episodes usually last from a few seconds to a few minutes, and sometimes they can persist for several hours.
I do not experience vertigo when looking at things.
I have seen an ENT specialist who diagnosed me with peripheral vascular insufficiency and prescribed medication for dizziness and vitamin B12.
However, my condition remains the same after taking the medication.
This has been ongoing for three weeks.
What other tests can I undergo?

Hello, based on your description, there are many factors that can cause symptoms of dizziness, such as anemia, autonomic dysfunction, and inner ear imbalance.
Recently, the weather has been warmer, so it is important to rule out dehydration as a cause of insufficient cerebral circulation.
You can improve symptoms by replenishing fluids and electrolytes.
I recommend discussing further examination and treatment with a neurologist.
Wishing you good health and peace.
Best regards, Taoyuan Medical Center.

More Info


Experiencing unexplained sensations of motion, such as a feeling of swaying or rocking, can be quite distressing and may have several underlying neurological or vestibular causes. The sensation you describe, which occurs regardless of your position—whether sitting, lying down, or walking—suggests that it may not be solely related to balance or equilibrium issues typically associated with inner ear problems.
Given that you have already consulted an ear, nose, and throat (ENT) specialist and received treatment for peripheral vascular issues and vitamin B12 deficiency, it is important to consider other potential causes. Here are some possibilities and recommendations for further evaluation:
1. Vestibular Disorders: Conditions affecting the vestibular system, which is responsible for balance, can lead to sensations of motion. Benign Paroxysmal Positional Vertigo (BPPV), vestibular neuritis, or Meniere's disease could be potential culprits. A vestibular function test, including electronystagmography (ENG) or videonystagmography (VNG), may help assess the function of your vestibular system.

2. Neurological Evaluation: Since your symptoms have persisted for three weeks, a thorough neurological evaluation is warranted. This could include imaging studies such as an MRI or CT scan of the brain to rule out any structural abnormalities, lesions, or other neurological conditions that could be contributing to your symptoms.

3. Anxiety and Stress: Psychological factors, including anxiety and stress, can manifest physically and lead to sensations of motion or dizziness. If you have been experiencing increased anxiety or stress, it may be beneficial to consult with a mental health professional. Cognitive-behavioral therapy (CBT) or relaxation techniques may help alleviate these sensations.

4. Blood Tests: While you have received treatment for B12 deficiency, it may be worthwhile to conduct a comprehensive metabolic panel to check for other deficiencies or imbalances, such as electrolytes, thyroid function, and other vitamins that could contribute to neurological symptoms.

5. Cervical Spine Issues: Sometimes, issues related to the cervical spine, such as cervical spondylosis or herniated discs, can lead to sensations of dizziness or motion. A physical examination and possibly imaging of the cervical spine may be necessary to rule out these conditions.

6. Medication Review: If you are taking any medications, review them with your healthcare provider to ensure that they are not contributing to your symptoms. Some medications can have side effects that affect balance and sensation.

7. Follow-Up with Specialists: If your symptoms persist despite initial evaluations and treatments, consider seeking a second opinion from a neurologist or a specialist in vestibular disorders. They may have additional insights or recommendations for further testing.

In summary, while your initial evaluations have not yielded definitive answers, there are several avenues to explore further. It is essential to communicate openly with your healthcare providers about the persistence and nature of your symptoms, as this will guide them in determining the most appropriate next steps for diagnosis and management. Remember that addressing both physical and psychological aspects of your health can be crucial in finding relief from these unsettling sensations.
