An allergy is when your body's immune system reacts to a substance as if it's harmful triggering symptoms like sneezing, itching or swelling.

Allergy in the lungs refers to allergic reactions that affect the respiratory system, causing symptoms like coughing and difficulty breathing. Common triggers include pollen, dust mites, pet dander, and certain pollutants.

Asthma, on the other hand, is a chronic lung condition where the airways become inflamed and narrow, making it difficult to breathe. Symptoms include coughing, wheezing, chest tightness and shortness of breath.
