My usually low BP shot up 2 years ago when I was sick. They convinced me to take the same medication you are taking; no one told me to stop riding! We already had a home BP machine, so I took it everyday. After 2-3 weeks I went back to the doctor and told them I was weaning myself off of the meds. I took my BP everyday and presented them with the printout of my numbers when I went back in. My BP is now between 90/72 and 120/78.
My BP routinely went up when I go to the doctor, until I started doing yoga and meditating. I just make sure I have no coffee or run up the stairs before I go to their office.
