Hi,Welcome to HCM,
It is possible that you might have got fungal infection
or bacterial infection due to severe itching
Clean the part with Betadine lotion and apply triple action cream.
Take one antibiotic medicine course.
take some anti histamine
like Cetrizine as and when required.
For fungal infection you may take oral antifungal
tablet like Flucanozole 150 mg once in a week for 4 weeks.
Ok and bye.
