This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
What is the color of the lump?
Also does it feel firm or soft?
Most likely this is a soft tissue lump arising from the underlying skin layer.
Fat cyst or lipoma is one condition.
Epidermoid cyst is anothe possibility.
These are all benign harmless lumps.
However can get infected with skin bacteria causing pain.
You can apply over the counter Bacitracin ointment over the lump to treat the infection.
Please get it checked by your doctor also.
They can be removed by a surgeon outpatient basis under local anesthesia.
It was my pleasure to help you today.
