Patient's question:
In August, I thought I was just gaining weight. But later, I felt something was wrong. It felt hard, didn't move, and didn't hurt.Doctor's answer:
Adult infection is often caused by the direct spread of epididymitis to the testis or hematogenous infection. Clinically, it is commonly referred to as epididymitis-orchitis. The pathogens are mainly Escherichia coli, Staphylococcus, and Streptococcus. Acute orchitis in children is often caused by the mumps virus.
