[|Human|] Hello, my son is 5 yrs and 6 month old. Every 2-3 days he develops balgam and coughs badly until he vomits and takes it out. Once he spits it out, he does not cough for next 2-3 days. We have observed this pattern for few months now and wanted to seek your expert advice.
[|AI|]  Hi, thank you for choosing Chat Doctor. Kindly get your child examined when he has the cough to rule out any wheezing and also to check his sinuses to rule out any sinusitis as these lead to episodic cough. If he is fine in between cough episodes and his general checkup is normal no need to worry. Hope this has been helpful to you, kindly feel free to contact again for any queries. Kindly rate the answer if so. Take care.  Chat Doctor.
