There are many causes of lumps or pain in the scrotum, including hydrocele, varicocele, and testicular torsion. Most lumps are not cancer, and many are not serious. However, you should always see a doctor if you have pain or a lump in this area.
You should always see a doctor if you notice any pain or swelling in your scrotum. If it is painful, you should seek advice urgently.

Why is there blood in my semen?
Blood in your semen often indicates a problem, but it is usually temporary and rarely serious. If it happens more than once or you have other unexplained symptoms, you should get checked out by a doctor to discover if there are any health issues that need addressing.

Testicular torsion
When a testicle (testis) twists around in the scrotum, the condition is called testicular torsion. An emergency operation is usually needed to treat this condition.

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).
Causes of pain or lumps in the scrotum
Common causes of pain or swelling in the scrotum include:

Uncommon causes of scrotal swellings or pain

Generalised oedema.
Allergic skin rashes.
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
The treatment totally 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.
