question: Hi, I have been on holiday and due to the air conditioning had a head cold/chesty cough. A week later I still have a cough, my chest is burning when I breathe and when I cough I have a horrid metallic/blood taste (no blood present though). I have taken no tablets other than paracetamol for the headcold. I can make an emergency appointment at my Doctors but don t feel it warrants an emergency appointment - yet! Do you think I have a chest infection? its the taste and burning sensation that is bothering me most. Thanky ou.
