Hi I can understand your concern for the suspected fungal infection of inner thighs near the private parts. It seems you have a fungal infection of the groin (inner thighs and private parts) referred to as tinea cruris. Antifungal creams containing Terbinafine or Clotrimazole or Miconazole are very effective in the treatment of tinea cruris. Apply the cream twice daily to the surrounding 4-6 cm of normal skin in addition to the rash. The following measures may prevent fungal groin infection (tinea cruris) from recurring: 1. Wash your groin daily; then dry thoroughly. The damp or moist groin is an ideal site for fungal germs to multiply. 2. Change your underwear daily. Fungi may multiply in flakes of skin in unwashed underwear. 3. Check for the fungal infection of the toes. The fungi from athlete s foot may spread to the groin. The same creams are used to treat fungal infection of the toes and the groin. 4. Do not share towels with people in communal changing rooms. Wash towels frequently & 5. Keep your own towel when you have a fungal skin infection to reduce the chance of passing on the fungus to others. Hope the suggestions given above could be useful in total eradication of the fungus from the goin (inner thighs and private parts).
