Go and see 10 docs about some problems, and you may get 10 differing opinions. (That's why it's called a medical opinion).
This shouldn't happen with BP treatment, the evidence is robust enough to avoid that dangerous medical attribute, "clinical acumen."
gingernut,
Just from reading your own post (the long one) it seems to me there might be quite a lot of scope for personal opinion in the case of people with bps of between 140/90 and 160/100. Eg slight personal history...not really sure what father died of actually, smoke the odd cigarette but very rarely, exercise but very intermittently...etc etc. Are you telling me every GP would agree on what ought to be done in such a case?
