I have had a mild cough for the past 20 days, mainly in the evening and at night. I have tried medicines such as Cortex, Bro-Zedex, Benadryl, and some Ayurvedic remedies, but there has been little improvement. What should I do?
A mild cough lasting 20 days, especially at night, may be due to post-nasal drip, allergy, asthma, or acid reflux. Since your current medicines have not helped, you should stop self-medicating and consult your doctor for a thorough examination, including an allergy and chest assessment, and to receive appropriate treatment. Stay well hydrated, avoid exposure to dust, smoke, and other triggers, and keep your sleeping environment clean and well ventilated until you are examined.
