Hi,
the point you 'seem' to have overlooked is I haven't had BCG - so on that basis since they don't know much about arthritus related to BCG and knew little related to immune reaction to cancer - what do they know about arthritus!
Keep a low profile if you see a chap with a divining rod, monkey skins, leopard cape and skulls strapped to his belt - that will be the new consultant!
If he has a small dog that keeps rushing up and sniffing you in an embarrassing manner it is clearly the new bladder cancer specialist.
If he has a divining rod, monkey skins, leopard skin cape, skulls at his waist, a small dog with embarrassing social habits and a huge brass telescope it is the new specialist from Indianna looking for Elaine to do a colonoscopy
