Why causes itchy bumps on scrotum?

There are several reasons you might feel itchy bumps on the scrotum. A fungal infection called tinea cruris, often known as jock itch, is a common cause. This infection creates red, ring-shaped patches or bumps that can be very itchy and sometimes spread to the scrotum.
Another cause is scabies, which is caused by tiny mites that burrow under your skin. In some cases, this can lead to small, hard bumps that are very itchy, as described in scrotal nodular scabies. Another possibility is scrotal dermatitis, a type of skin irritation where the scrotum becomes red, inflamed, and develops small, irritating bumps. This form of dermatitis might be triggered by an allergic reaction or skin sensitivity.
