Quick answer
What is Varicocele?
A varicocele is a collection of enlarged veins within the scrotum, caused by the valves in the veins not working properly so blood pools — much like varicose veins in the legs. It is common, usually develops on the left side, and is often described as feeling like a "bag of worms" above the testicle.
- How it is treated: Many varicoceles need no treatment, especially if there are no symptoms.
- Self-care: For mild discomfort, supportive underwear and simple pain relief may help.
- When to seek help: See a GP for a new scrotal swelling, aching or a "bag of worms" feeling, so it can be examined.
What it is
A varicocele is a collection of enlarged veins within the scrotum, caused by the valves in the veins not working properly so blood pools — much like varicose veins in the legs. It is common, usually develops on the left side, and is often described as feeling like a "bag of worms" above the testicle. Many varicoceles cause no problems, but some lead to a dull ache or heaviness that is worse on standing or after activity, and they are sometimes linked to reduced fertility or, in adolescents, slower growth of the affected testicle. Diagnosis is by examination and, if needed, an ultrasound scan.
How it is treated
Many varicoceles need no treatment, especially if there are no symptoms. When they cause bothersome pain, affect fertility, or are associated with a difference in testicle size in a young person, treatment can be considered. This involves a procedure to seal off or tie the affected veins, done surgically or by a catheter technique. The decision is individual and made with a specialist, weighing symptoms and any fertility concerns. Supportive measures such as scrotal support and pain relief can help mild symptoms.

Beyond medication
Lifestyle and self-care
For mild discomfort, supportive underwear and simple pain relief may help. There is no proven way to prevent a varicocele, but reporting a new scrotal swelling or aching for assessment is sensible.
When to get help
When to see a doctor
See a GP for a new scrotal swelling, aching or a "bag of worms" feeling, so it can be examined. Seek urgent care for sudden severe testicular pain, which can signal a different, serious problem.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
