[/INST] HelloSevere cough may be due to many reasons like infection, allergy,carcinoma etc. You may need clinical correlation and further investigations. Empirically you have taken right antibiotics, but underlying etiology should be searched. Besides clinical correlation, routine investigations, initially chest X-ray (PA view)should be taken. CT scan of thorax may be needed after evaluation. Treatment depend upon findings. Get well soon. Take Care Chat Doctor.  </s>
