The last 2 days I've had a typical cold and carried on as usual. This morning I have no energy and my chest feels tight and I feel short of breath. I don't have a cough and don't think I have a temp but just feel rubbish. Work tomorrow and not sure what to do. I get anxious about falling ill so that may play a part in the chest tightness & I had pneumonia this time last year. Otherwise fit & well.
