Re: Itchy groin/under belly fat rash
It could be a fungal infection, like a yeast infection or something like that. You could try an antifungal cream from the drug store (generally found near the foot care products, creams with active ingredients ending in -azole). It could just be moisture irritation, which would require some sort of powder, like baby powder or talc powder or something. If those don't work, I'm sure a general doctor would be able to diagnose it.
