Thanks for posting this question in HCM
Let me explain you that a given medical symptom is due mainly to various causes and the aim of the physician is to find out the exact cause and deal accordingly rather than simple assumption.
Back to your questions i understand that you have headache on-off for the past 4 months
Let me tell you that headache can be due to various reasons like migraine
, brain tumor
, brain infections, problems in the blood vessel of the brain and high blood pressure
and so on etc. One point of concern to me is that you have two Blood pressure readings that are high (sorry that i donot know your age and gender). Under this scenario, it seems likely that it could be related to episodic blood pressure elevations too. I strongly advise you to undergo medical evaluation by a physician and neurologist
who will determine the exact cause of elevated blood pressure and deal accordingly. The neurologist who will examine you will be able to guide regarding he need of a brain scan. I advise you again to undergo medical evaluation without much delay.
Hope this will help and guide you.
