An itch in the groin area. Many people who suffer from severe itching in the pubic region do not realize that this could well be a ringworm infection. The ringworm infection is actually a fungus, and as such, it thrives in warmth and moisture. This makes it very common in the groin area. However, since it is commonly called a jock itch, people don’t always connect that term with ringworm. A visual confirmation of symptoms is also rare.
