Thanks everyone for reading my anxious rambles. I have been to the GP and he has reassured me that I can refuse to speak to an intern or reg, and insist on only speaking to the consultant when he has his next appointment. He also says I can easily transfer to private once I have been seen at outpatients and they have decided on a mode of action - I can find out who is the best person to oversee the treatment and transfer at that point but right now he doesn't know who would be best and feels that even if I do have to wait 2 weeks that it will not affect the treatment or recovery.

So slightly less annoyed and frustrated now.
