Thank you for asking your query on ATD.
What we can see on your mandible is a simple boil.
Some of the boils liquefy and burst out in the form of pus. Some are stubborn and remain as a small lump. There is a possibility that it is infected acne or it can be cystic acne.
You are advised to consult your physician who may examine and advise you further treatment. He may give you a course of antacids and analgesics.
You may require minor incision and drainage.
