An individual's blood pressure is not a static phenomonon, but varies from minute to minute and day to day. Sometimes there may not be a very good reading from home BP units. Some individuals take their home BP unit with them to a doctor's office to compare.
BP pressure should be averaged for a more accurate assessment, and your BP does not rise to a level of be cause much concern.
Hope this helps, and if you have any further questions or comments you are welcome to respond. Thanks for sharing, take care,
