Signs and symptoms of scrotal masses vary depending on the nature of the abnormality. In some cases, the only sign may be the presence of a lump in the scrotum that you can feel with your fingers.

Scrotal mass symptoms may include:

  • An unusual lump in the scrotum
  • Sudden pain
  • A dull aching pain or feeling of heaviness in the scrotum
  • Pain that radiates throughout the groin, abdomen or lower back
  • Tender, swollen or hardened testicle
  • Tender, swollen or hardened epididymis (ep-ih-DID-uh-mis), the soft, comma-shaped tube above and behind the testicle that stores and transports sperm
  • Swelling in the scrotum
  • Redness of the skin of the scrotum
  • Nausea or vomiting

If the cause of a scrotal mass is an infection, symptoms may also include:

  • Fever
  • Urinary frequency
  • Pus or blood in the urine

When to see a doctor

Seek emergency medical care if you develop sudden pain in your scrotum. Some conditions require prompt treatment to avoid permanent damage to a testicle. See your doctor if you detect a lump in your scrotum or experience other symptoms of a scrotal mass.

Some scrotal masses are more common in children. See your doctor if your son experiences symptoms of a scrotal mass, if you have any concerns about the development of his genitals, or if he is "missing" a testicle — an undescended or retractile testicle, which may increase the risk of some scrotal masses later in life.
