Hello. Thank you for writing to us at healthcaremagic I will keep a possibility of fungal infection/tinea cruris. The location and the fact that it itches goes in favor of a fungal infection. Groin folds is a common site for fungal infections because of the anatomy. The closely apposed body folds favor moist, warm conditions in the groin folds which allows the fungus to proliferate and form itchy patches. A KOH wet preparation made from a small amount of scale scraped from the rash to look for fungal elements will help confirm the diagnosis. I suggest you to try an OTC topical antifungal e.g clotrimazole 1% cream, twice daily at the itchy patches. An Oral antifungal e.g fluconazole Or terbinafine may also be required if the patches are extensive. An OTC oral antihistamine e.g cetrizine 10 mg once daily will provide you symptomatic relief from itching. Regards
