I had to leave you all, because I was freezing all of a sudden. I grew so short of breath too.I threw myself in bed for a few minutes. then I thought I must turn the heater up, even though it's 22 degree. I put a bean bag in the microwave, then put it round my neck which had "seized" with cold. I proceeded to make anew pot of tea and drank some with some Paracetamol. I phoned a nurse where my wife stays who said I'd done the right thing. I'm so scared of these freezing bouts.
