Not quite the same, but I've recently had an issue with a nurse practitioner when I believe I should have seen a GP at the start. I have got an appointment for urgent "2 week wait cancer referral" biopsies next week for lymph nodes which I'm concerned about, but I had to request a second opinion from a GP to actually get the referral.
I'd seen a nurse practitioner the first time I presented to the surgery and he told me that despite the fact my lymph nodes had been raised for 3 months (with no apparently cause) and despite the fact I'd also developed drenching night sweats with excruciatingly itchy legs (with no cause), he had no real concern.
He thought the breathlessness I've developed was anxiety so told me to "breathe slowly" when I'm breathless and that the lymph nodes were probably from an infection I didn't realise I'd had. I asked if that was the case, why hadn't the gone down after a few weeks and he said "you just have overactive lymph nodes". I asked if he could say this for sure without at least a scan and he told me to book a blood test but didn't think a scan was necessary. He had no explanation for the night sweats but said the weather had been warm recently. I did point out the weather is warm every year in the summer but I'd never had night sweats before, which he didn't respond to. He briefly felt my neck but I know he didn't feel my lymph nodes as he didn't press on the raised ones, despite me trying to show them where they were.
Unhappy with this, I phoned up and asked for a second opinion from a GP and got an appointment the following week. The GP didn't understand the nurse practitioner's lack of concern, brought someone in to do blood tests there and then and referred me for urgent biopsies. The GP said I was right in seeking a second opinion.
While a nurse practitioner is someone who is qualified in their own right and does have extensive medical knowledge, I still think the nurse practitioner should have known the criteria for an urgent referral and I still don't understand why he was so unconcerned. If I'd taken his advice I would not be awaiting a biopsy and, if it does turn out I have something nasty, I would be much further behind in the process of sorting it. I only asked for a second opinion because my DP really insisted that I should, but the nurse was so confidence in his assurance that I was absolutely fine I really felt no need to, I'm so glad I did though.
