Glad your still kickin Zed !
you asked :Has anyone else had BP spikes when in a similar situation? OH YES !!! I have been treated for high blood pressure since my thirties (it runs in my family ) But even on meds when I am anxious ,which I especially get in medical environments , my BP shoots sky high ! When I was being prept for surgery the nurse kept telling me she hoped I didn't stroke out on her ...that didn't help btw. This last surgery I told them about my anxiety before hand so they gave me something to take right away, and things went much better .
I also found some relaxation music videos on you tube to listen to when I get anxious ,and they seem to really help .
