Hello again everyone,
I returned the BP machine to the nurse yesterday. She was pleased with my results and stated that no further action was required. She also took my BP whilst I was there, with an electric monitor, which turned out to be 159/89. High again! I was disappointed that I couldn't hold it together after demonstrating all week to myself that my BP is ok (average = 123/75 82BPM).
My next move is to return home and get my BP measured in familiar surroundings. If I can manage three 'normal' readings on three different days I'll be fine for the CAA.
Regards, QQ
