My wife is 34 years old, weighing 45 kg she had previous C/S scar four years before for our first child since she became eclamptic (Hypertension, edema & convulsion). She gave second birth 25 days before under operation (C/S). since giving birth she develop persistent dry cough & mild fever. for this she took natural remedies, Amoxilllin for seven days, paracetamol tabs & Polaramine syrup. Now the fever has subsided but still she has intermittent dry cough & throat pain. What shall we do to alleviate the cough. Thank you.
