I have spent most of this morning coughing up great lumps of green stuff and my throat hurts, my chest hurts and my lungs feel like they are on fire.

I can understand having nerves my chest to feel broken ribs and throat to feel choking but inside my lungs?

Why would the body bother having nerves there except to make my lungs burn at the moment.

My GP once told me that your lungs can feel no pain. So any pain is presumably muscular or from other areas in the region.

Yeah, I don’t think lungs should feel pain but it definitely inside and feels like fire when I breath

if you had no nerves in your lungs you wouldn’t feel the need to cough up the green slime…

Gizzards generally have no nerves don’t they?

Lungs have receptors (if that is the right decription) that sense when there is a build up of mucus they then cause you to cough. This is designed to clear the mucus as it cannot be absorbed by the lungs.
