<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a 10 month old male who is projectile vomiting after milk feeds... he is quite chesty, teething and coughing a lot. The vomiting started yesterday at childminders, no diahorria and nothing different to normal apart from a bump on the cheek that is now a bruise.  <response>: Thank you for consulting in Chat Doctor. I need more details:1. Did he receive his vaccination against pertussis?2. What character of cough, is it most Chat Doctor. Did he have breathlessness on lying flat? 4. Has his cough been finished with vomiting?5. Is there any relief when she walks outside?6. Did she eat something spoiled or with dirty hands at childminders? If she has these issues we should differentiate pertussis, bronchitis, foodborne toxicoinfection. To begin with, give to child eco normsaccharomyces 1 packet 2 times 3 days. For cough, you can use relentsyrup, erythromycin, steam inhalation or do inhalation by nebulizer with albuterol, then after 15 min with aerosol. Best regards
