Symptoms of scrotal lumps and swelling

The symptoms depend on the cause of the problem. Possible symptoms include:

• Noticing a lump which has not been there before.

• A sudden pain.

• A dull ache.

• Redness or warmth of the skin of your scrotum.

• The testicle (testis) or structures around it may be very tender.

• Swelling of your scrotum.

• Feeling sick (nauseated) or being sick (vomiting).

• Having a temperature, passing urine more frequently, or pus or blood in your urine (if the cause is an infection).

What tests are used for scrotal lumps or pain?

Your doctor will often be able to tell what kind of swelling it is just from examining you. For example, they may shine a light through your scrotum, as fluid will light up. Or they may ask you to cough which may make a hernia more obvious.

You will usually have an ultrasound scan to be sure of the cause and to find out whether you need any treatment. An ultrasound scan is a painless test that uses sound waves to create images of organs and structures inside your body. Sometimes a blood test may be helpful too.

Treatment for scrotal lumps, pains and swelling

The treatment depends on the cause. Often no treatment at all is needed. Other times - for example, in testicular torsion or testicular cancer - treatment is needed urgently. See each individual leaflet for further information on the different treatments.

NB: always see a doctor for advice about whether treatment is needed.

Blut im Sperma

Haematospermia means there is blood in the semen. Usually there are no other symptoms such as pain. In men under 40 years old it is usually harmless and resolves without any treatment. However, it can also be caused by a number of conditions that need investigations and treatment.
