Ring them, or do an online consultation - that is what most people are having to do before seeing a GP. We've had a number of needs as a family to have medical assistance over the last few weeks and they are doing all the can to avoid anyone coming to the surgery at the moment. My daughter had three long consultations during a 12 hours period with the GP who rang her back a number of times.

I'm terrified but feel I need to get peace of mind over this lump in breast. I'm mostly confident it's OK but have that niggle feeling it isn't.
The 'peace of mind' won't come through a potential visit, you just KNOW it won't !
