Doctor: hi,
thanks for posting your question on Health.is.edu.

there is a high possibility of this lump being an abcess.

you will need a   antibiotics such as amoxycillin and then you will need an x ray

the x ray will determine if you have a

the treatment for both varies is

please DO NOT apply heat, this tends to spread the infection around the face.
