Welcome to HCM,
The disease you have ,is sebaceous cyst
Do not worry, it is benign condition.Oral antibiotics
may be taken with anti inflammatory drugs.
After clearance of infection , it should be removed surgically under local anaesthesia.
If it is not removed, it may reappear.
Have blood test
to rule out DM and HIV ,before surgery.
You consult dermatologist
I hope you got my answer.
