This is Dr. David
it sounds like you need prescription antifungal treatments.
bad jock itch can take 6-8 weeks of continuous twice daily antifungal powder like nystatin powder and antifungal creams like ketoconizole to treat bad jock itch
also you might benefit from oral fluconizole antifungal creams.
you have to see a doctor to get prescription treatment for your fungal infection.
let me know if you have other questions.
