While I agree that some people misuse the NHS, I think in many areas, there is a lack of alternative services and they are not well signposted or easily available.
I am rural but about 8 miles from the nearest town. There is a GP surgery in the next village. It would, in all honesty, knitting fog would be easier than getting an appointment.
You can never book in advance as all the appointments are always taken
there is 4-6 week wait on those.
So, you ring at 8am and spend 45 minutes on hold to be told 'no same day appointments left'.
There is a 7 day access service - I tried them twice - fully booked.
111 is frankly not great. Again, up to an hour on hold, to be told you need a GP appointment. Except you can't get one (see above) so 'a doctor will ring'. Waited until 8pm one night for a call regarding my son's ear infection- still no one had called.
You ask about nurses - no appointments with them either.
We did have a (well used) walk in centre in town but it closed in March 2020 and is now permanently closed 
In fairness, our village pharmacy is pretty good but can't prescribe things like antibiotics.
I need relatively regular physio due to a spinal problem. I pay privately for that as the NHS list is so long and the one time I went, they couldn't have been less interested. Think they realised it was a long term problem and didn't want me taking up regular appointments.
All of the above are largely due to lack of adequate funding but it does make it very difficult for people.
I'm fortunate not to require medical attention often but I can perfectly see why people become frustrated and go to A&E.
