Hi Lemery Thanks for coming to HCM It seems that yoy have a lower respiratory tract infection following viral upper respiratory tract infection, with possible secondary bacterial infection. It is very urgent to suppress your cough to prevet incisional hernia or bursting of the surgical wound. Go for a chest xyay PA view, sputum for acid fast bacilli, gram staining and culture and sensitivity. IN the meantime you must try stronger cough suppressants like syrup codeine phosphate along with antihistaminics like cetrizine along with as needed inhaled salbutamol via rotahalers. antibiotics like azithromycin will be helpful. wear a belt to support your surgical wound... yes if there is some secretion from the incision site you must meet your doctor.... best wishes
