Hi, thank you for writing on Healthcare Magic.
I have gone though your query and understood your concerns.
All these symptoms you have listed could have resulted from high blood pressure
. What you described as "terrible migraine" is a complication of high BP (Malignant hypertension
) called hypertensive encephalopathy
. Also, blurred vision
is one of the symptoms of malignant hypertension. Once you have these symptoms and nothing is done immediately to bring down the BP, you run the risk of a stroke.
I hope I have answered your query
I wish you good health
