Thanks for your query
You seem to be having Candidiasis
of the groin region.
First some general precautions:
Wear cotton clothes and undergarments in order to reduce the sweating.
Do not apply any kind of oils / moisturizing lotion over the affected area .
Just give warm saline compresses over the affected area twice a day and then apply an antifungal cream.
You are already using monistat which is miconazole
cream and it helps in most cases.
Also , you will need to take oral antifungals 2 weeks.
In case of severe itching
, take some antihistamine once a day .
If inspite of the above measures, the lesions continue to persist or increase , then you might have to see a dermatologist
for proper assessment and management .
Hope it helps
