Ganglion cyst

A ganglion cyst is a fluid filled lump under the skin that usually appears on the wrist or hand. Ganglion cysts are common and often get better on their own. There are treatments if it's painful or affects joint movement.

Symptoms of a ganglion cyst

Ganglion cysts are smooth, soft lumps under the skin that:

• are usually on the hands or wrists near a joint – but can be on the top of your foot
• vary in size, from smaller than a pea to a few centimetres across
• are usually painless but can be painful during or after moving the affected joint

The lump may be your only symptom, but you may also have numbness or aching after moving the affected joint.

How to treat a ganglion cyst yourself

Ganglion cysts usually get better without treatment, this can take from several months up to a year.

If a ganglion cyst hurts when you use your hand, there are things you can do to treat it yourself.

Do

• take ibuprofen or other non-steroidal anti-inflammatory drugs (NSAIDs) to help reduce swelling and pain

• try wrist supports or compression wraps (a stretchy bandage made of elastic) – you can buy these from supermarkets or pharmacies
