Hi,
Thank you for posting your query.
Your symptoms need to be evaluated. It is possible that you have migraines, which get aggravated in specific postures.
High blood pressure can also cause
headaches in about 10% of people. So, lowering the blood pressure to normal levels would reduce the headaches.
Certain BP medications such as
amlodipine can also cause headaches.
If no cause can be identified, then, a brain scan should be done.
I hope my answer helps. Please get back if you require any additional information.
Wishing you good health,
