Oh Nidge - what a muddle! What do you want to achieve by changing hospitals? To see the same consultant each time you visit? That isn't guaranteed whichever hospital you are under - consultants will always have housemen taking their clinic appointments, particularly for what they see as straightforward cases. Could you just have a second opinion at another hospital first and ask at the appointment whether they would provide any better continuity of care before you make a complete change? Perhaps it would be worth paying for a private consultation (might cost about £250 - £300) to ask the questions you need. Or are you planning to move to Nottingham where you have already seen someone?
I don't think getting there quickly should be much of a consideration. If you needed emergency care, you would presumably go to your nearest A&E anyway?
Does r'lass understand how serious your diagnosis was? You shouldn't really have to cover your own feelings to make other people feel better ... or at least, I don't think you should. On the other hand, if their anxiety is because they feel you are over-reacting to seeing different doctors when in their experience that's just how it is in the NHS then perhaps you could try to accept it a little more? We see the same onco and uro every time but we pay for the privilege. For my own health situation, I never see the same person twice but it doesn't really bother me - I just keep track of what was said and put them right if necessary :-0
