Coughing is one of the most common reasons why people visit their doctors. When symptoms last for more than a few weeks, the cough would be diagnosed as being chronic. The most common causes of chronic cough include post nasal drip, asthma and acid reflux. Post nasal drip, caused by allergic rhinitis, and asthma certainly could be caused by allergies, which could be worse seasonally.
Have you noticed that your cough seems to be worse along with your seasonal allergies? It is certainly possible for a cough to be worse seasonly, which may mean that the cough is due to asthma or post nasal drip caused by seasonal allergic rhinitis. Allergy testing may reveal positive testing for tree or grass pollens, and pulmonary function testing may reveal signs of asthma. A therapeutic trial of medications for allergic rhinitis or asthma may be helpful at differentiating the cause of cough.
