Hi, bout of cough
I have noticed in many patients, reasons are thousands. In your's case it may be due to inhalation of some thing in trachea, 2nd reason may be due to congestion and allergy
in lung due to some allergens. If rales ( wheezing
*WHISTLE*) type of sound is there pl take some bronchodilators and some cough syrup containing codein phosphate but after the advice of of doc.
