I have a weird sensation in chest and throat, can anyone relate?

Hi All,
I think my question may not last long.
I have weird sensation in my chest and throat.
It’s really challenging to describe. I have a cold and I’m coughing.
It feels like an air bubble is rising up and I have to cough, when I do it feels better, but then will come back. It doesn’t hurt, doesn’t cause any weird breathing issues. It just feels really weird.
Another way to describe it would be tightness creeping up that goes when I cough? An air bubble or pressure building?
Anyone have any ideas?
My Dr can see me in two days – can’t afford Accident and Emergency and I’ve had it for 24 hours. Thoughts?
