Ganglion Cysts

What is a Ganglion Cyst?

A ganglion cyst is a common, non cancerous lump that forms near a joint or tendon. It most often appears on the wrist or hand, but it can also develop on the foot, ankle or knee. The lump is filled with a thick, jelly-like fluid and can feel soft or firm. Its size may change over time and often varies with activity.

For many people, a ganglion cyst causes little trouble. For others, it can lead to pain, stiffness or weakness if it presses on nearby nerves. Some cysts are easy to see, while others are hidden under the skin and only noticed when they begin to cause discomfort.

If you are concerned about a lump or your symptoms are affecting daily life, book an appointment with one of our consultants.

Symptoms of a Ganglion Cyst

A ganglion cyst often appears as a visible lump under the skin. You may notice that it changes in size over time and can feel soft or firm to the touch.

Other symptoms can include:

Pain or aching near the affected joint, especially with movement.
The feeling of stiffness, weakness or a tingling sensation if the cyst presses on a nearby nerve.
Some people have no pain at all and only notice the swelling.

Causes of a Ganglion Cyst

The exact cause of a ganglion cyst is not always clear. It is thought to develop when fluid leaks from a joint or tendon and collects under the skin, forming a lump.

Repeated movement or strain on a joint may increase your risk. Previous injury to a joint or tendon can also play a part. Ganglion cysts are more common in the wrist and hand because these joints are used often in daily life.

How a Ganglion Cyst is Diagnosed

A ganglion cyst is often diagnosed with a physical examination. Our consultants will ask about your symptoms and check the size, shape and position of the lump. They may also shine a light through it to see if it is filled with fluid.

If the diagnosis is not clear, you may be offered an ultrasound scan or an MRI scan. These tests help confirm that the lump is a ganglion cyst and rule out other causes.

Treatments for a Ganglion Cyst

Treatment for a ganglion cyst depends on your symptoms. If the cyst is not painful and does not affect movement, you may not need any treatment. Some cysts disappear on their own over time. Most ganglion cysts are harmless and do not lead to long term problems.

If you have pain or limited movement, your consultant may suggest using a splint to rest the joint. Aspiration may also be offered. This involves draining the fluid from the cyst with a needle. In some cases, a small operation may be advised to remove the cyst if it keeps coming back or causes ongoing issues.

When to get medical advice

You should seek medical advice if the lump is painful, growing, or limiting your movement. If you notice numbness, tingling or weakness in the affected area, this may mean the cyst is pressing on a nerve. It is also a good idea to get a lump checked if you are unsure what it is, or if it causes worry. Early advice can help you understand your options and decide if treatment is needed.
