Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that swollen
upper lip and
sneezing seems to be probably due to
allergic reaction only and in case if it has happened after giving
Ibuprofen, it can be due to allergic reaction to Ibuprofen..
It can however be due to other causes like allergic reaction to any food, animal danders, pollen, trees and grasses, etc..
I would suggest you to give him anti allergics like Allegra or
benadryl..
You can also replace Ibuprofen with Tylenol to reduce fever..
Do cool compresses over the lip..
In case if the symptoms recur then consulting an Allergist and get evaluated and an allergic test can help in confirmation of cause and treatment can be done accordingly..
In case of allergic reaction anti allergics can be advised..
Hope this information helps..
Thanks and regards.
