[|AI|]  Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query your father-in-law have symptoms of persistent cold and cough which seems to be due to upper respiratory tract infection or poor immunity of body. Need not worry. He should avoid exposure to allergen such as smoke and any smoking article as that will exaggerate their condition. Avoid intake of cold carbonated beverages. Avoid intake of sharp spicy food. Visit ENT specialist once and get it examined and start treatment after proper prescription. You should maintain oral hygiene. Do warm saline gargles. You can go for blood and sputum tests as well. You should take proper course of antibiotics along with anti-inflammatory medications. Furthermore, you should apply mist humidifiers in room and take throat lozenges.
