I've been riding this commute for over 2 years, this is the first time anything like this has happened, so maybe it was a combination things, stress may have been a factor since work's been a little busy lately. I might not have eaten or drank enough the night before.. etc.
I was looking at the paper the emt gave me, the blood pressure they have listed when they first got there was 180/120. Normal is around 120/80. I've never had any medical issues before, so it's just crazy to me.
