Hi i have a smelly itchy groin with a slight rash and large skin tag,can you help please as the smell is getting embarrasing.

See Your Doctor Now: Description suggests possible Tinea Cruris (aka Jock Itch). a fungal skin infection; thrives in warm, moist areas (groin, inner thighs, buttocks); treated with anti-fungal meds. Thorough bathing, drying needed daily to prevent recurrence. Visual inspection is required to diagnose your rash & "skin tag"; also your medical history is not given.
