Been to doctors this morning recent visit to out of hours.
Went in doctor says 'how can I help you' I explained to him of my hospital visit and reason, he listened to my chest and stated all was very clear, not a crackle to be heard, must have been a viral infection, blood must be coming from clearing my throat-small blood vessels.
Then he said, I will send you for a chest x-ray, had to tel him they did that on the night, oh he said, was there anything showing up, I said no I was told all was OK.
The then asked me if I had any health problems, I did say I was concerned of the crackling lung due to me having bullous emphysema, oh he said I had better check my notes. Sorry but do they not look at these things before a patient comes in!
Anyway after 10mns I cut my losses and left, lungs ok, he put it down to a viral infection.
