<bot>: Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that it is important performing a comprehensive differential diagnosis of different possible causes that may lead to this clinical scenario: an inner ear disorder, chronic degeneration of the cervical vertebral column, orthostatic hypotension, vertebro-basilar insufficiency, etc. For this reason, I would recommend consulting with his attending doctor for a physical exam some tests: - a cervical spine X-ray study- a resting ECG- a Doppler ultrasound of the carotid arteries-thyroid hormone levels - complete blood count for anemia-fasting glucose- a Head Up Tilt test for orthostatic hypotension. If all the above tests result normal, I would recommend consulting with an ENT specialist and performing labyrinthine tests to investigate for an inner ear disorder. Hope you will find this answer helpful! Kind regards,
