Our GP isn't letting people in either, but they are generally OK for making phone appointments on a convenient day in the future for routine things (medication reviews etc). Everything else seems to be on the day phone calls with an indication (but no guarantee) of which hour it may be in. Annoying enough for me at home, but it must be a nightmare for people who can't just drop everything for the possible hour window. Though I suppose in the past you'd have had to take the time off to go to the surgery, so it's six of one...
I've just got a slowly building list of things that I think I should see someone about at some point, but it's not urgent so I don't want to take an emergency appointment, and can't guarantee to be available for the entire day anyway. A pharmacist may be a good call - even if just to say whether or not it's something I need a GP for, and what level of urgency
