I don't think your symptoms are related. You probably had a type of fungal infection like "gock" itch in the groin area and that went away. The ear issue could be an ear infection or clogged ear. You should see a doctor for that. Nail fungus is common and they can either give you anti fungal pills for it if they are yellowish nails or the doctor can take a look and see what it is by the color.
