Hi and thanks for the query,
Clear running nose with no signs of alteration of his general health condition should be suggestive of a viral infection. Upper respiratory tract
infections in children are usually viral. It is however important to know why he is vomiting
. How is the nature of the vomiting? What are the possible drugs he has been taking lately? has the child been given his worm medicines regularly?
A few of these factors could lead to vomiting and usually ceases with time. However, if this persists a more detailed evaluation might be required. This could involve a complete blood count
and C reactive proteins to exclude a probable bacterial infection and urine analysis for urinary tract
infections, commonly expressing themselves as such in children. However, I think you need to be calm and watchful again for a few days. In case of anything setting in or persistence of the symptoms, consulting his pediatrician
for a complete review shall be the best thing to do.
Thanks and hope this helps,
