I'm really struggling with a persistent fungal infection between my legs that's been bothering me for the past few months. I've tried using antifungal creams like Soframycin, Fourderm, and Betnovate N, and while they seemed to help initially, the infection always returns after a few days, especially around my private parts. Can you suggest any stronger or more effective antifungal treatments that might help clear this up for good? It's starting to really concern me.
