I had a blood pressure reading of 224/144 today at the hospital - what danger am I in if I do nothing about it

I went to hospital after a big impact to the head. They advised that I MUST go to my GP to follow up my blood pressure. The two readings were 224/144 and 214/163 taken ten minutes apart. I am 25 years old and had a blood pressure of 180/140 in my first year at uni 7 years ago. It is possible therefore that I have been hypertensive all this time. I often have headaches (6-7 times per week) too. Am I putting my health in excessive danger now or can I leave it for a few more years yet - what would the consequences be of doing nothing?

I had my blood pressure taken by an Emergency Nurse Practioner (Triage) - The doctor I saw about my head did not mention my blood pressure so I did not think to ask her - I guessed if it was important she would have checked it herself or offered me advice.

Okay, keep very calm. I dont want to scare u & make your blood pressure rise anymore, but u have the highest blood pressure I have ever heard anyone to have.
My advice to u is to instantly & calmly pack a suitcase & make plans to be away from home for a long time. Then get at some hospital because u are on the verge of getting a heart attack or a stroke. The hospital will want to check u in because there is no way that they are going to let u return home with blood pressure that high.
