Hi Seonaid, welcome from me too. Sorry to hear about not being able to contact you nurse, it's awful. I was lucky with mine last week, in so much pain i rang the wrong department and ext number very early and left a message.

A very thoughtful person passed it on and i got a call back within a couple of hours from the nurse.
Maybe this would work for you too, go on give it a try.
Hope your feeling better soon. Kathleen x
