Hello and thank you for using HCM.I carefully read your question and I understand your concern.
I will try to explain you something and give you my opinion.
You should know that we talk about
hypertension if we have mean value that exceeds 140 / 90 mmHg.A person might have high value during emotional and physical strees so its mandatory to judge on mean values.
During a hypertensive crisis a person might experience headache,
blurred vision,
dizziness,
nausea.A very hight bood preassure might couse neurological demages.
So, it is mandatory to treat
high blood pressure.
My opibion is that you should not worry. You are experiencing headache only becouse of high values.If a neurological damage happens the situation is worse and acute.
If I was your treating doctor I will recommend some examination like a cardiac echo to evaluate heart function and walls, a full blood analyze to chek renal function, a holter pressure monitoring to evaluate your values during day and night.
After this I would recommend a good antihypertensive treatment and than we can do the MRI to chek the neurological situation.
Hope I was helpfull.
Best regards, Dr.Ervina
