I've had the same thing happen with my blood pressure which is normally 117/69. and varies very little. I take my blood pressure twice a day every single day (morning on rising and at night before retiring) so I'm quite familiar with it. I do this because I had an ablation procedure 12 years ago and want to make sure AFIB never comes back. So far it has not. Last time at the doctor's office (urgent care for sour throat because my personal doctor had resigned) I waited 2 hours in a mask before being seen. My BP was 148/88 with a puls of 78.. So far no AFIB. Sore throat could not be explained but went away after 10 days. Since then, I limit my mask wearing to 10-15 minutes. Long enough to quickly get in and out of the grocery story., I order anything else I need on line. I also NEVER wear a mask twice. I buy KN95 masks and once I wear one I wash it by hand before wearing again.
