I think that doctors would disagree with the too young. While it may be unusual to your age, it is possible. Hypertension can lead to strokes. A child in the local elementary school had a stroke at the age of six. Untreated hypertension has in some studies been linked to the development of dementia. 

I hope they sent you home with meds and a referral to a clinic that offers income based care.

As someone who, thankfully, has no lasting effects from a cryptic stroke before the age of 35, I cannot stress enough how serious hypertensive crisis can be.  Perhaps more so in younger, otherwise healthy, people due to assumptions of age being on your side. 

My health was picture perfect all of my life.  Until my stroke woke me up in the middle of the night.  It was minor, I literally walked myself into the ER.  Intake thought my symptoms were some sort of allergic reaction.  The tip off?  My normally very regular blood pressure was through the roof.  They kept me in the hospital for a week despite the fact that my symptoms had fully abated within the hour before the scans were back.  I was too young, too healthy, for there to be clouding on the film.  They were all flabbergasted.  I saw, and continue to see, more specialists than I could have imagined.

While I have no lasting physical effects, and several years later the specialists can't figure out what did it, the two tiny clouds on my scan mean the rest of my life will be very different from someone without them.

I had a headache earlier that week.  I brushed it off as nothing serious, thought maybe I was unlucky enough to start experiencing migraines.  Took some OTC medication that just kind of dulled the pain.  My BP was a little high for me, I assumed from the pain, but not even registering pre-hypertension levels never mind crisis levels.  Stroke was nowhere near being on the radar.  I was 34.

Your symptoms sound like a TIA.

That may never escalate into something with permanent damage, even without change.  But please don't take the risk.
