Thanks guys.

I don't want to keep bothering my GP as I felt I've really really hassled her so much since being back in Cornwall.

Maybe if I just ask for a telephone appointment tomorrow then they might put me on to another GP.

It's always good to know. Apart from FBC, can anyone else recommend a good test I should have done? I'm more than happy to give them a pint of my blood and do what tests they want with it!!
