Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of having breakouts around lips of your daughter that causes pain , swelling and bumps along with yellowish crust can be due to conditions like
Impetigo that is a bacterial infection, eczema or less chances but can also be due to Viral infection in case if there are clusters of bumps..
I would suggest you to
consult a Dermatologist and get her evaluated and a clinical evaluation can be sufficient but if required for confirmation culture and sensitivity testing, blood tests can be done for confirming the cause..
The Dermatologist can advise antibiotics, anti- inflammatory medicines and
topical antibiotic ointment if it is bacterial infection..
Antiviral medication Oral as well as topical like
Acyclovir, Valacyclovir can be given in case of Viral infection..
Eczema can be treated with Steroids..
Hope this information helps..
Thanks and regards.
