Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
The history you have given appears to be concerning and it will require proper evaluation. An MRI
scan of the brain should be good. Many times aneurysms can present with such symptoms.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
In future if you wish to contact me directly, you can use the below mentioned link:
Wish you good health,
Dr. Srikanth Reddy M.D.
