Hi. I went to GP on Monday and he said I have a viral infection and he gave me antibiotics for 5 days , finishing them tomorrow. I have been coughing very violently and there is a gurgling sound in my upper respiratory/throat and I can't get my breath when coughing so much, not coughing up much, green phlegm in the mornings, but thick white later In the day (sorry a bit too much info). Is this part of the viral infection or something else? The bubbling in my throat when coughing is very scary as I can't get my breath, any ideas?
