Most people have experienced a cough caused by a cold or flu — the kind of cough that comes on strong for a few days during an illness, and then tapers off as you start to feel better. But what if you have a cough that just won’t go away?
Find an allergist
If you have a chronic dry cough (a cough that has lasted for more than three weeks), it may be a symptom of allergies or asthma.
If your cough is allergy-related, you might notice that you cough more during some seasons, or in some environments. This can be caused by the presence of allergens that may affect you.
You might also have other symptoms of allergy. Hay fever (allergic rhinitis) can cause sneezing, congestion, and itchy skin, eyes and nose, as well as a cough. Congestion from allergies can also cause dark circles, called allergic shiners, to appear under your eyes.
An allergy cough is caused by your immune system’s response to an allergen, rather than by an infection like a flu or cold cough. Asthma can also cause a cough. If you are also wheezing or have tightness in your chest or shortness of breath, you may have an asthma cough. Your board-certified allergist is a specialist in helping patients find relief from symptoms like asthma and allergy cough.
