pnd and colds at the back of the throat that cause bad smell of my mouth...what to do?
Acid reflux is an often over looked cause for sinus and throat problems from PND, sinus infections, hoarse voice. Acid can even be aspirated and cause asthma like symptoms. Many people are miss diagnosed with asthma that really just have very bad acid reflux. When the acid reflux is controlled, their asthma goes away. The formal name for this type of asthma is laryngeal-pharyngeal reflux.
Good doctor too consider that possibility. I hope that the treatment works for you.
