Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns...
As per your complain recurring lumps on the
upper lip that are painless and does not cause any discomfort but recurs every after a few days can be due to causes like
allergic reaction to any lip cosmetic or can be due to
herpes simplex virus 1 infection causing cold sores..
For a confirmatory diagnosis, you should
consult a Dermatologist and get evaluated and a thorough clinical evaluation and investigations like blood tests can help in diagnosis and treated accordingly..
In case of allergic reaction anti allergics like benadryl or Levocetrizine and avoiding exposure to the allergen once it is detected in the blood test can be done to resolve the recurrences..
In case of viral infection oral and topical antiviral medicines like
Acyclovir can be advised..
Hope this information helps..
Thanks and regards..
Dr. Honey Nandwani Arora..
