I wish I had a solution for you. Same thing happens to me. About once a year my BP registers as very low even though I'm on BP medication and my BP (usually)remains a little high. Each time this has occured in the morning between the hours of 8 and 11am at the doctor's office. The last time it happened was in March of this year. I switched doctors and my chart went missing at the former GP's office. I told my new doc that I was out of BP med and needed a script for more. My BP was something like 100 over 60-something. She changed cuffs and the reading was within a few points of the original reading. She had me wait a while and took the BP again. It was still very low. A return trip the following week showed high blood pressure: 160-something over 90-something. I never felt different or strange when the BP was low.
