Five years ago I was diagnosed with high blood pressure. I was prescribed amlodipine. At the time I was employed in a high pressure job but I was told that I would probably have to keep taking the medication. Since I retired my blood pressure reduced considerably so in consultation with my GP I stopped taking the drug. After a few months my blood pressure started rising again, so I went back on amlodipine. I also measure my blood pressure regularly.
When I measure my own blood pressure the readings can vary considerably. For example, this morning I took ten readings. The highest was 140/68, the lowest was 104/60 and the average was 125/63.
With these readings I am unsure if I have high or low blood pressure. In terms of my health which reading should I use? Also, is this sort of variation normal and what is its significance?
