hi, Thanks for posting the query
you seem to have recurrent boils
in that area
It may be due to bacterial infection or even fungal
you can do as follows:
Maintain proper hygeine
keep the area dry.
use a mild soap or cleanser
dont rub or itch instead take anti histamine
if it itches too much
Apply antibiotic cream like mupirocin
twice a day till it persists.
If it reoccurs contact a doctor to rule out any systemic cause
Hope this answers your query
