Severe itching in groin area. Dark pink small patches. Have been applying Neosporin powder and cream but but limited and temporary effect. Seems to be some fungal problem.

Severe itching in the groin area with dark pink small patches is likely indicative of a fungal infection, such as jock itch (tinea cruris). In addition to Neosporin, which is an antibiotic and may not be effective against fungi, you should consider using an antifungal medication. I recommend using Lotrimin Ultra cream twice daily for 2-4 weeks. Additionally, keeping the area clean and dry, wearing loose-fitting clothing, and avoiding sharing towels or clothing can help prevent the spread of the infection.
