Hi, It seems that probably you suffer from fungal infection on upper inner thigh, called tinea cruris. It is caused by fungus called dermatophyte. It may be precipitated or exacerbated by certain factors like perspiration,excessive water contact,soap,DM,immune deficiencies,nutritional deficiencies..etc. never apply steroid cream as you applied, as it might increse the condition. You may take antifungal like tab ketoconazole or cap itraconazole for few weeks. Antihistaminics like levocetirizine may be taken till itch is relieved. Apply clotrimazole cream. You may feel better. You have eczema also. Take treatment under observation of dermatologist. I hope you got my answer. Thanks. Dr. Ilyas Patel MD
