Chest congestion/infection

So not strictly about my type 1 (although it is increasing by blood sugar levels!) but really grateful for any advice on this ... the past couple of days I've had a chesty cough and a bit of a feverish feeling (no actual high temperature). My chest kind of hurts/burns when I force a cough to loosen the congestion.

I can't get a GP appointment for 2 weeks (!) but just wondered if anyone thought this could just be a common cold / viral infection I've picked up or is likely to be something more sinister or something requiring antibiotics?

I don't have the classic cold symptoms of runny nose / headache / sore throat so a bit worried this chest congestion could be something more sinister. I feel perfectly fine other than the congested chest so don't think it's pneumonia. Still have a normal appetite and able to go about day to day as normal.

Thanks so much for any advice guys; I'm a bit of a hypochondriac so always worry about every symptom.

Thanks for those links, @JTL.

In one of them they comment as follows:

“Unfortunately, in most cases, unless the patient has another underlying chronic condition for example, heart or lung disease or diabetes, there is often nothing the GP can do to help other than recommend resting and drinking plenty of fluids"

What exactly can doctors do differently for those of us with diabetes?
