Hi,
There can be many causes of vertigo. Good, you have got some many investigations done already. It will make the diagnosis easy.
See we need to have a detailed history and clinical examination for that. One of the most common causes is diseases associated with ear like
labyrinthitis (infection of the ear),
vestibular neuritis (inflammation of the nerves), or BPPV (benign positional vertigo).
It can also be related to diseases of the brain (infection or swelling) or heart disorders (arrhythmia- rhythm disturbances) or
cervical spondylosis (neck posture-related issues).
Besides this, there are simpler causes like anemia (low
hemoglobin),
hypoglycemia (low sugar), prolonged fasting, excessive heat, stress, anxiety or lack of proper sleep. Hence, I feel, first of all, focus on lifestyle modifications.
Have a well-balanced diet with lots of fruits and vegetables and less tea and coffee. Maintain proper posture while working and sleeping, take good sleep for 7-8 hours, do some
meditation, or go out for a walk.
Do not be depressed or tense about it. If still the symptoms persist then do go for some investigations like- sugar levels, electrolytes, ECG, X-ray
cervical spine and MRI brain. If possible go for ENT examination also. This will help us to make a proper diagnosis.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr. Milinda Gupta
