Based on the symptoms you described—dry cough for a month, worsening at night or after waking up, but absent during the day at work—a few possible causes come to mind: Possible Causes: Postnasal Drip (PND): Mucus dripping from the nose into the throat at night can trigger coughing. Can be caused by allergies, sinus issues, or mild infections. Gastroesophageal Reflux Disease (GERD): Acid reflux can irritate the throat, causing nighttime or early morning cough. Often worsens after lying down. Asthma or Airway Hyperreactivity: Cough-variant asthma presents with dry cough, often worse at night. No wheezing or breathlessness may be present initially. Environmental or Allergy-Related Triggers: Bedroom allergens like dust mites, AC exposure, or dry air can trigger night cough. Mild Viral/Post-Infectious Cough: A cough that lingers after a viral infection can last for weeks. What You Can Do: ✔ Steam inhalation before bed to soothe airways. ✔ Saline nasal rinse (if postnasal drip is suspected). ✔ Avoid eating late at night if reflux is a possibility. ✔ Use an extra pillow to elevate the head while sleeping. ✔ Try a humidifier if the room air is dry. If his cough persists or worsens, I recommend seeing a pulmonologist for spirometry (lung function test) to check for asthma or airway sensitivity. Hilar Adenitis on X-ray: What Does It Mean? Hilar adenitis (enlarged lymph nodes in the lung hilum) can occur due to various conditions. Since your husband has a dry cough for a month, worse at night/morning but absent during work, this finding should be evaluated further. Possible Causes of Hilar Adenitis: Tuberculosis (TB) – A common cause, especially in India. If TB is suspected, further tests like Montoux test (TB skin test), IGRA (TB blood test), and sputum tests may be needed. Sarcoidosis – An inflammatory condition that can cause hilar lymph node enlargement. Usually diagnosed via HRCT Chest and blood tests. Respiratory Infections – Certain viral or bacterial infections can cause temporary hilar lymphadenopathy. Fungal Infections or Other Granulomatous Diseases – Less common but possible. Lymphoma (Rare but should be ruled out if symptoms persist) – Usually associated with weight loss, fever, or night sweats. Next Steps:
