My blood pressure reached these levels a few years back.
I'd had no history of high blood pressure previously. I went to the doctors as I felt out of sorts but was whisked to A&E as they were so concerned it could be a heart attack, stroke or blood clots. Within minutes a cat 1 ambulance was being called and dh was called to come and meet me too. It was all really quite alarming.
I had various tests, bloods taken and ecg. My heart rhythm etc was fine and they found no evidence of these things.
What they did discover was that I had covid and it was linked to that.
I was kept in for a couple of nights.
In that time my gp stayed high even with medication.
By the time I came home the top number it was around 180-210 still.
I was put on medication, which was added to a week or so later as it was still too far too high.
I got a home BP machine and took my readings 3 times a day and it did start to reduce.
That was almost 4 years ago now. I'm still on the medication and likely to remain on it.
I have 10mg amlodophine and 5mg Ramoril these days.
My Bp is normal now most of the time,
