A prolonged cough not improving with medicines may be due to conditions like Chronic bronchitis, Asthma, Gastroesophageal reflux disease, or infection such as Tuberculosis. Avoid self-medicating further; stay hydrated and avoid dust or smoke exposure. It is important to consult a doctor for proper evaluation, which may include a chest examination or tests like X-ray, so the exact cause can be treated appropriately.

Throat pain with cough is usually due to a viral throat infection or irritation; drink warm fluids, do salt-water gargles, and avoid cold or spicy foods. You can take Paracetamol for pain and fever, and use lozenges or steam inhalation for relief. If needed, an antihistamine like Cetirizine may help with cough due to allergy. If symptoms persist beyond a few days, worsen, or you develop high fever or difficulty swallowing, consult a doctor.
