Hi,
Thanks for asking the query,
According to your symptoms i suppose that you had developed an ulceration on your upper lip.
This can be due to the hormonal changes, nutritional deficiencies, poor
oral hygiene, dry mouth, GIT disturbances,
sinusitis, inflammation of gums that had spread to the vestibule.
I would suggest you to visit the
Dentist and get the checkup done.
Go for symptomatic treatment of complete mouth scaling and polishing.
Consult a Physicain and get the checkup done, go for treatment of
xerostomia.
Take
multivitamin tablets.
Take complete balanced diet, drink plenty of water and keep yourself hydrated.
Maintain a good oral hygiene, take antiseptic mouthwash twice daily.
Apply Dologel oral ointment topically over the affected area.
Hope this helps out.
REGARDS.
