It's nation wide but there are some areas which are really bad...especially nhs wise.
My dentist shut down, due to lack of staff, the nearest dentist (both private and nhs) that I could get taken on by (2 years later) was an hour away (lucky to get this)..... and is (relatively affordable) private. On the news a few days ago out of 60 dentists in Norfolk, NONE are currently taking on patients.
My local hospital (King's Lynn), which is one of only 3 'full size' nhs hospitals in my entire county, is basically being held up with 1500 wood and steel props and getting to see a doctor at my local gp is near impossible.
NHS care in the UK, especially where I live, is dire and imo we need to change the NI system to be sort of a 'medical insurance' allowing us to go to whoever is available rather than the current system.
And I'm going to be honest, it's not just the current governments fault, they haven't helped, but this all started a long time ago.
