<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, There is a small around the size of a quarter or a little bit bigger red rash on my inner thigh, that every once in a while at least twice a day itches. It hasnt spread, but it wont go away. It also has an odd smell to it. There arent any bumps on the rash or anything either. Do you know what this could be or how to treat it?  <response>: Hello. Thank you for writing to us at Chat Doctor I will keep a possibility of fungal infectionTina courts. 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 terminating may also be required if the patches are extensive. An OTC oral antihistamine e.g. cetirizine 10 mg once daily will provide you symptomatic relief from itching. Regards
