Thanks for posting your query. Your symptoms suggest of an sebaceous cyst
in that area. The cyst has to be removed for complete clearing as per your doctor's advice to get rid of it completely. Usually the procedure does not produce any scarring if properly sutured.
If you have difficulties in undergoing this, as you mentioned I only suggest to take some antibiotics to reduce the infection, especially when it becomes bigger.
include only hot fomentation to reduce the inflammation and vitamin c
