This could be a boil( furuncle
). To help it heal, do hot water fomentation twice in a day and apply an antibiotic cream like mupirocin
or fusidic acid
. To help relive pain and inflammation surrounding the lesion, you may take an antiinflammatory pain killer like ibuprofen
. Do not wear tight clothes as too much friction over the lesion can impair early healing. If the lesion does not seem to respond much, kindly consult a doctor nearby to initiate a course of oral antibiotic.
Hope that answers your query.
