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. Closely opposing body folds e.g finger webs, thighs/groin, axilla, submammary folds etc can trap sweat, heat and moisture, therefore making the area prone to Intertrigo. If I was the treating doctor I would have asked to use a topical antifungal like clotrimazole/sertaconazole/luliconazole cream, twice daily, regularly for 4 weeks. An OTC antihistamine e.g cetrizine syp, 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
