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.
Not alarming actually, but you do need to get investigated. MRI
scan of the brain will be required as this could be due to an aneurysm
. However there are other trivial reasons as well like hypotension
or cervical vertebra degeneration etc.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
