I have not heard back from my request for further information.
There are several common causes of sudden onset of coughing, bubbling in chest and a burning sensation.
I ask about shortness of breath, because the presence of shortness of breath would indicate that you should be seen urgently, regardless of the underlying cause. Shortness of breath that is associated with a cough that is productive with purulent sputum or fever would also be worrisome for a bacterial pneumonia.
It is also possible to develop the coughing and associated symptoms from a bornchitis, which is usually less serious, although also can need urgent care if there is shortness of breath.
Acid reflux also can cause coughing, bubbling and a burning sensation. If a significant amount of acid gets into the lungs, it can cause significant shortness of breath related to an aspiration pneumonia, which also should be addressed urgently.
If you are not having any shortness of breath, purulent sputum, or fever, then it is more reasonable to try some home remedies for relief of symptoms, such as a cough syrup that contains a suppressant, such as dextromethorphan, or a medicine to offset stomach acid, such as a liquid antacid, ranitidine, or omeprazole.
