Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have boils on inner lips and cheek don't worry it can be due to vitamin deficiency or due to Periodontal problem that is due to poor oral hygiene.  Don't worry you Apply ointment McCoppin 2 - 3 times a day on painful area of lips and cheek.  Take one capsule vitamin B complex twice daily for 15 days Maintain proper oral hygiene by regular brushing use chlorhexidine mouthwash 2 times a day. Consult dentist for oral prophylaxis. Hope this will help you. Wishing you good health.
