Ganglion Cysts 

What is a Ganglion Cyst?

A ganglion cyst is a fluid-filled swelling that usually develops on the hand or wrist, often near a joint or tendon. These cysts are common and, in many cases, will settle on their own without treatment. However, if a ganglion cyst is painful, restricts movement, or causes concern, treatment options are available.

Symptoms

Ganglion cysts are typically:

• Smooth, soft lumps under the skin
• Most often found on the wrist or hand, but they can also appear on the foot or ankle
• Variable in size, from smaller than a pea to a few centimetres across
• Usually painless, but may cause discomfort, aching, or numbness after using the affected joint

For many people, the visible lump is the only symptom.

Self-care

In many cases, ganglion cysts improve naturally over time. This may take several months, sometimes up to a year.

If your cyst is causing mild discomfort, you may find relief from:

• Taking over-the-counter pain relief, such as ibuprofen, to ease pain and reduce swelling
• Using a wrist support or compression bandage to help with discomfort during activity

Important: You should not attempt to burst or puncture a cyst yourself, as this can cause infection or damage to the skin.

Treatment Options

If your ganglion cyst is painful, unsightly, or interfering with movement, our specialists can offer several safe and effective treatments:

• Aspiration – draining the fluid from the cyst with a fine needle
• Surgical removal – a minor operation to remove the cyst completely

While surgery usually prevents the cyst from returning, there is a small chance it may reappear.

Why do ganglion cysts form?

The exact cause of ganglion cysts is not always clear. They may develop after a joint or tendon injury, when fluid leaks out and collects under the skin.
