The surgery rang back on Monday evening, after The Old Man's INR blood test in the morning, to tell him what dosage of Warfarin to take.
And by the by - his next blood test would be in "two weeks time".
The Old Man exploded. Told 'em that he needed two blood tests a week until his INR level had stabilised - cos it is still up and down like yoyo.
Reception rang back later to say that he could in fact have the twice a week that he wanted for now.
It left The Old Man puffing like a Grampus - but victory was his.
I tell you, sadly but with the wisdom of experience, - take nothing from GPs on trust. And stick to your guns. If you know where they are.
