Thanks for writing your query.
Symptoms described by you are suggestive of asthmatic bronchitis
. Vomitting can occur due to excessive coughing.
You should get the following investigations done :-
1. Complete Blood Count
2. Absolute Eosinophil
3. Chest X-Ray PA view
Please get yourself examined by a chest physician.
You should take nebulization of bronchodilator
as it will help you fast.
Also take antiallergy along with the above medication.
I hope this is helpful to you.
