These symptoms may be related to allergy, but other causes are possible, such as gastroesophageal reflux disease (GERD), an upper respiratory tract infection, or environmental irritants. That symptoms are worse in the morning and improve during the day suggests an allergic pattern or exposure to triggers present at night. Note whether you are exposed at home to dust, pollen, pet dander, or tobacco smoke. If you have emergency signs such as fever, severe cough or sputum with blood, shortness of breath, or altered consciousness, seek immediate emergency care. For symptoms lasting longer than two weeks, worsening symptoms, or if they significantly affect daily life, consult your family physician, an Otorhinolaryngology (ENT) specialist, or an Immunology and Allergic Diseases specialist. Low-risk home measures that some people find helpful include regular bedroom ventilation, avoiding tobacco smoke, frequent washing of bedding and pillowcases, and tracking symptom triggers — discuss these with a health professional before making decisions.
