Hi Ms Christina,
Thank you for posting your query.
I have noted your symptoms. It is less likely that your symptoms are fully due to old
head injury that you suffered in 2005.
Generally, the effects of head injury would go away in a few weeks time.
Do you have any CT or MRI brain report? What was the nature of brain injury?
We need to repeat another MRI of brain to find out the reason for your current symptoms. Possible causes may include
ischemia (lack of blood supply to the brain),
brain tumor, etc.
As of now, you can take
betahistine tablets to relieve the
dizziness.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
