Hello and welcome to healthcaremagic I would keep a possibility of Intertrigo, which is inflammation of the body folds. There is superimposed candidal infection in most cases (Candidal Intertrigo). Clinically intertrigo presents as red, moist, scaly patches of skin on closely opposed body folds. Foul smell is mostly due to bacterial overgrowth. Closely opposing body folds e.g thighs/groin, axilla, submammary folds etc can trap sweat, heat and moisture, therefore making the area prone to Intertrigo. Wearing a pad provides occlusion and thus further aggravate the condition If I was the treating doctor I would have asked to use an OTC topical antifungal like clotrimazole cream, twice daily, regularly for 4 weeks. An OTC antihistamine e.g cetrizine 10 mg tablet, once daily would help in symptomatic itch relief. An Antifungal dusting powder e.g clotrimazole dusting powder, would not only keep the area dry but also inhibits the growth of fungus/yeast thus preventing recurrence. regards
