... it relieves for less than 4 days and then it comes again..when he cough,he can't stop for almost 1 minute till he got vomited and than silent for a few hours and repated again,i took him to a pediatrician for 4 times and they had given him start from spiramicin(7 days),cefixim(5 days),cefadroxil (5 days),he's x-ray showed nothin but a little plaque of sputum and now i'm confusing..what should i do..by the way he had an allergic genetic from both of me and my husband..is it an allergic cough?
