What happens when crabs is left untreated?

If crabs, or pubic lice, are left untreated, the infestation can lead to persistent itching and irritation in the affected area, which may result in secondary bacterial infections due to scratching. Over time, the discomfort can affect daily activities and quality of life. Additionally, untreated crabs can spread to sexual partners or other close contacts, exacerbating the problem. It's important to seek treatment to alleviate symptoms and prevent transmission.
