question: I have had very low blood pressure all my life. I'm 47 and recently have high pressure when it is checked. I have headaches frequently and understand this could be related. But I also notice that no matter how much sleep I get I still feel exhausted. Is this possible another symptom of high blood pressure? In all honesty I have been very sedentary this winter. As an avid hiker (4-6 miles per day)so this is unusual for me and no doubt why the pressure is up. So perhaps this is also why I feel so tired?
