Since the itching in your private area and between the hips has continued for almost a month, even after using Fintrix 250 mg and Fintrix cream for 2 weeks, it is possible that the infection may not be fully responding to the treatment or the problem could be something other than a simple fungal infection. Sometimes conditions like eczema, allergy, bacterial infection, diabetes, excessive sweating, or steroid cream misuse can cause similar symptoms. Medicines/treatment should be taken only if advised or prescribed by your doctor. Try to keep the area dry and clean throughout the day. Wear loose cotton underwear, avoid tight clothing, and change sweaty clothes quickly. Avoid scratching because repeated friction can worsen irritation and delay healing. Do not apply random creams or powders without proper medical advice. Consult a doctor if the rash is spreading, becoming painful, developing cracks, foul-smelling, or causing severe itching at night. A proper examination may help identify the exact cause and suitable treatment.
