Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain sudden swelling of the lips that has gone away in few hours and also recurred seems tobe most probably due to ALLERGIC
ANGIOEDEMA and is caused due to causes like allergy to any food or medicine while any skin cosmetic or
bug bite etc can also be a cause..
You should consult an Allergist and get evaluated and he can advise allergic tests like RAST test,
Patch test, Food Challenge test etc to confirm the exact cause for the symptoms..
As of now you can take anti allergics like Allegra or
Claritin and also do cool compresses over the lips..
Avoid licking or sucking the lips..
The Allergist can also give you
steroid shot if swelling is in excess..
Hope this information helps..
Thanks and regards..
