Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns.
As per your complain recurring swelling on the side of face that changes sides seems to be due to
allergic reaction to some unknown allergen and it can be due to any food or medication,any cosmetic used on face while can also be due to
drug abuse..
It does not seems to me like an infection as if it would have been due to infection it would have not switched sides of face..
I would suggest you to consult an Allergist and get evaluated and it will be better if you go when the swelling is present..
If he suspects Allergic reaction then he will advise him to go for allergic tests like
Patch test,
RAST test and food challenge test to rule out the exact cause of allergic reaction and treat you accordingly..
In case of allergic reaction avoiding exposure to allergen can help..
He can also be advised to take anti allergics like
Allegra or Levocetrizine to reduce the allergic symptoms.
Hope this information helps..
Thanks and regards.
