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.
