Thanks for writing in.
The condition you are suffering from can be tinea cruris
. It is a common fungal infection
Treatment consists of antifungal drugs.
Keep the area clean and dry.
Apply lamisyl cream twice daily.
Wash all your clothes with antiseptic added water.
Avoid sweating and wetness in the area.
The infection should subside by 2-3 weeks.
Lamisyl cream is available over the counter without prescription.
Hope this helps.
I will be available for follow up.
