The three common causes for chronic cough are allergy, asthma and acid reflux.
Allergy, along with non-allergic rhinitis and chronic sinusitis, result in post nasal drainage that triggers a cough. Acid reflux irritates mucosa near the voice box that triggers mucus production, and subsequent cough. Asthma is a lower respiratory tract source for chronic cough and is often associated with periodic audible wheezing. Correct diagnosis is crucial for symptom resolution. Call to schedule consultation and evaluation if you are suffering from chronic cough.
