What is a ganglion?

A ganglion is a lump under your skin that contains fluid.

Ganglions usually form near joints. 3 in 4 ganglions form near the wrist. They are also found on your ankle and foot.

The fluid in the ganglion comes from a joint or tendon through a narrow channel.

What are the benefits of surgery?

The lump and any discomfort from it should settle. Surgery gives the best chance of preventing the ganglion from coming back.

Are there any alternatives to surgery?

A ganglion will often disappear or become less painful after a year or two. If your ganglion is not causing much trouble it is best to leave it alone.

The fluid can be taken out of the ganglion using a needle.

Your doctor may also inject the ganglion with a steroid (cortisone).

What does the operation involve?

Various anaesthetic techniques are possible. The operation usually takes 15 to 30 minutes.

Your surgeon will separate the ganglion from the nearby tendons, nerves and blood vessels. They will remove the ganglion from where it comes out.

How can I prepare myself for the operation?

If you smoke, stopping smoking now may reduce your risk of developing complications and will improve your long-term health.

Try to maintain a healthy weight. You have a higher risk of developing complications if you are overweight.

Regular exercise should help to prepare you for the operation, help you to recover and improve your long-term health. Before you start exercising, ask the healthcare team or your GP for advice.

Speak to the healthcare team about any vaccinations you might need to reduce your risk of serious illness while you recover. When you come into hospital, practise hand washing and wear a face covering when asked.
