Let the GP take charge now, Catkins. He's obviously terrified and this will make his perception of pain worse. You've done all you can to help him and it's very hard when you are struggling to keep your head above the water yourself.

Seeing the GP in person will allow for a proper examination and he'll be able to talk about his cancer fears.

Please let us know how he gets on and I hope this takes the pressure off you a bit.
