4 years after taking aspirin daily as prescribed by the doctor, during a non related appointment he said I was to stop taking them. "Why?" "Because they don't work."
That was it, no further comment on the matter.
Thinking back, there was a day when I accidently cut a finger slightly. Nothing to shout about really except I just could not stop the blood flowing. Drove to the A&E and a couple of stitches cured it. Nurse, during the procedure, asked if I was taking aspirin, "yes" "thought so, thins the blood, sometimes too much."
Could that have been the answer? Have never been told otherwise. Already on the 'old age' medication as I call them, seems to be enough, there being no alternative to aspirin.
