My baby is 8 months old has a cough that does not go away ...

Doctor I Need Urgent Help! My baby is 8 months old, at 40 days he had a chronic viral bronchitis, he was hospitalized for erythromycin for 14 days ... since then he was discharged, and he never had bronchiolitis again, but he has a cough that does not go away, , or sleep that the cough comes, has crises terrives during the dawn ... about 8 crises per night, some of them it seems that he will not come back so choked that he stays, already took in pediatric mtos, and no one knows how to solve, just prescription antiallergic like polaramine, and rinofluimicil to drip on the naris, but nothing solves, at 8 months he takes daily remedies and nothing works, I do not know what to do or who to turn ... please help me if you can!

Expert answer:

I can not tell you what your baby has, but by history he may have Gastro-Esophageal Reflux Disease or a lung or respiratory disease that really needs to go to the pulmonologist, go back to the pediatrician.
