OK, so MY adrenalin surges (can't speak for anyone else) were when i was going through an 18 month long period of ongoing stress at work. About 3 different stresses, all layered on top of each other.
Something would trigger the experience (phone going, waking up in morning and the first thought was to run like a hamster on a wheel through my work To Do list, or surprise bad news), and i would get that fight or flight response, like a surge running through me.
Bp shot up.
Also heartbeat.
Mind started racing.
Could also almost feel the adrenalin squirting through my bloodstream.
Even dreams could set it off, and i had broken sleep for the whole 15 months.
Totally disproportionate response to a phone ringing, i think you will agree?
It was like my stress response was on a hair trigger, and overtime, and bonus pay.
I tried stress managing techniques;meditation (which i do anyway), breathing, hot cocoa, sitting in garden, dog walks (which helped), but i couldn't flick the hair trigger off, all i could do was reduce the size of the surge when it happened.
After about 15 months of this, i was somewhat depressed and rather stressed, and a routine bp test highlighted some alarmingly high bp.
Was given 5 mg Amlodipine for the bp, with the expectation i would need 10mg, and poss additional medication.
And the surges just switched off with the 1st tablet. Sleep improved. I could handle the stress ok (it carried on another 3 months) but what had been ripping me apart was the surges. Placebo effect? Possibly. Don't care. It was SUCH a relief.
So now, the bp seems to be fine, the stress is gone, and if i forget the Amlodipine, i haven't noticed any surges. But i am rather concerned that any life stress could re-arm the hair trigger, if you know what i mean.
I'm hoping that my next medication review is with the excellent nurse (not the NHS parrot one, or thejobsworth one), and she will let me keep the Amlodipine. It is probably a forlorn hope.
