"Experienced cared, just a shame about the nhs"

Waited a year for a referral for my headaches after a hospital admission last year. Doctor I saw from the Walton Centre was very professional and gave me multiple choices to help combat them. That's all I needed. It's taken a whole year to get this appointment, gp had been prescribing medications that weren't helpful for that entire time. What on earth has happened to the NHS that appointments are taking that long?
