Thanks for query,
Sir you are right in your diagnosis but half right in the treatment !
Now lesion is infected,so go for an antibiotic course.
apply triple action cream for short time.
Go for oral antifungal
tab. Flucanozole 150 mg once in a week for 4 weeks.
After lesion becomes dry,go for anti fungal cream.Never bandage.
Take antihistamine if itching is there.
Ok and bye.
