I am sitting at home waiting for a PCR result right now. I am 99% sure I have the same kind of chest infection I have been getting for 30ish years now, but the GP quite rightly sees my double jabbing and weeks of clear lateral flow tests as irrelevant. I have a cough that needs treatment, I get a PCR. The cough is leaving me light-headed, so enforced seclusion is not entirely unwelcome.
