Several points were raised by the last couple of posts, not all to do with high blood pressure.
" As for the dangers of the Medical and Health Forum, couldn't agree more."
Well, potentially; I agree there are dangers. However, I think one can reasonably assume that the users of this forum are intelligent, highly interested and motivated in maintaining good health, and will have to work with a qualified physician/AME to keep flight medical status. Hence they will be unlikely to self-medicate or otherwise cause themselves harm.
Mostly it's about shared experience tho commiseration and sympathy also appear. I noted metoprolol appearing a couple of posts back but assumed that was ironic, not serious, advice.
A wrist monitor might be useful if as Primary Care says, properly calibrated, used correctly, and, ideally, cross-checked with a "proper" measuring instrument - which for blood pressure is a mercury sphygomanometer or similar with the correct size of cuff. If these conditions are met then terrific, yes, but Female Wannabe's experience shows how easy it can be to get wildly inaccurate results, which - as in this case - could be highly alarming.
It isn't difficult to get your BP checked by someone (eg a practise nurse) who knows how to do it correctly, is using the proper kit, and understands the significance of the results. If you really want to go on checking it yourself, ask what the numbers were, so you can at least see if you are in the same ball-park. But ask yourself - do you know what is high, low or normal? Do you know what level of blood pressure "matters"? No? Then perhaps leave it to someone who does?
If there really is a problem surely any competent physician would verify the results for him/herself before making a decision about treatment or not - which is what your specialist is presumably doing, Irish Steve, not relying on your measurements.
May all your blood pressures remain low(ish).
