Thank you everyone! All the posts are interesting, and I'm somehow not surprised that so many of you have gone down the private route. Yes, I agree that it shouldn't be necessary and we pay a lot for the NHS which just seems to fail so many of us, but this isn't an ideal world.
That said, this also isn't a political discussion, just a practical one! I'm fed up of feeling rubbish and if I can do something to speed up diagnosis and/or treatment then I will. I've had a health anxiety issue for ages now, and I just want it sorted one way or another.
I'm glad a lot of you had positive outcomes, that's encouraging.
Silverlady: thank you for the link.
Hurdity: spot on, that's exactly what I meant!
