Hello doctor,

My dad has been treated with angioplasty 6days back due to one blockage affixing one stent for the treatment. Post that on day 4 he has been discharged. Now since last 2-3 days he is continuously having cough due to which he hasn't been able to sleep and causing distress. Whenever he is lying down for sleep cough irritates him and he is forced to sit. Please suggest what should be done.

Thanks.
