Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your complain the swelling inside the
upper lip can be due to either injury caused by the teeth or any hard food causing inflammation and swelling or it can be due to
allergic reaction to certain foods..
While in case if it is in the form of a small lump it can be a Mucocele formed by either clogged duct of minor
salivary gland or ruptured duct of gland.
You need not to worry as if it is a
swollen lip it will gradually resolve on its own..
If there is itching or any other symptom associated with it you can take
benadryl which is an anti-allergic medicine..
If it is a lump which can be a mucocele do concentrated salt water rinses as it will help in resolving it..
If the swelling does not go away in 3 to 4 days consult an oral physician and get evaluated..
Hope this information helps..
Thanks and regards..
