Diagnosis

Your doctor will start with a physical exam. It's likely to include:

• Checking for tenderness in an enlarged scrotum.
• Applying pressure to the abdomen and scrotum to check for inguinal hernia.
• Shining a light through the scrotum (transillumination). If you or your child has a hydrocele, transillumination will show clear fluid surrounding the testicle.

After that, your doctor might recommend:

• Blood and urine tests to help determine if you or your child has an infection, such as epididymitis
• Ultrasound to help rule out hernia, testicular tumor or other causes of scrotal swelling
