Re: what is a GP?
they're usually all booked up weeks or months in advance
I can usually get an appointment with my GP in England within 24 hours, though I usually make a point of telling them that it's not an urgent problem. I guess I'm lucky to be registered with a well-run village practice.
By way of contrast, a friend who couldn't get an appointment with her GP went to an NHS Walk-in Centre. They told her she seemed to be in serious need of treatment, but she would have to come back at 6 o'clock. When she did so, she was told that there were no available consultations (but they agreed that she seemed to be in serious need of treatment).
So much for the on-demand Walk-in Centre. She ended up in A&E.
