Signs and symptoms of scrotal masses vary depending on the abnormality. Signs and symptoms might include:
- An unusual lump
- 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, signs and symptoms also might include:
- 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, even if it's not painful or tender, or if you 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 might increase the risk of some scrotal masses later in life.
