That does put a different light onto it.
I assumed this latest guy was just telling you you don't need any further appointments. If he was making an alternate diagnosis, especially based opon one meeting, then it's probably a wind up from the local group of Drs.
That he is an Arab is, I have to say, utterly irrelevant.
You're fighting the NHS. They have unlimited resources and almost unlimited power. I made one complaint, when I was 16 and am still paying for it, 40 years later.
