Well, I was back at 3.30. Lost again lots of blood (there is a card in the 'blood room' which starts: Dear Bloodsuckers) As for the travel going by car takes as long as bus and tube and there is almost no parking available. This is a very old hospital in Chelsea, so no car park included when it was built. And as a holder of a Freedom Pass it doesn't cost me a penny. Anyway they still can't find what caused me to be so breathless on Monday. None of tests show anything that shouldn't be there. I am pleased that tomorrow's appointment was cancelled and I am back on Monday. I admit though to being tired and I might be late getting up in the morning. We will see.
