A ganglion cyst is a smooth, fluid-filled lump that forms next to a joint or tendon, most often on the back of the wrist. It is filled with thick joint fluid that has leaked from the joint capsule and become walled off. It is not a tumour, and it is not dangerous. The lump can come and go, change size with activity, and is sometimes tender or achy, especially with wrist movement. Around half of all ganglions settle and disappear on their own over months or years. Most ganglions do not need any treatment at all. The first job is confirming the diagnosis, sometimes with an ultrasound or other imaging if anything looks unusual. If the lump is not painful and not in the way, watching and waiting is often the right call, since many resolve on their own. Drawing the fluid out with a needle can settle some, though the cyst refills in a fair proportion, because the sac and its root remain. Surgery is kept for ganglions that keep causing pain, keep coming back, or where the diagnosis is not certain. The operation removes the cyst together with its root, the small stalk connecting it to the joint, which is the part that matters for stopping it coming back. Removing the stalk brings the chance of it returning down to around five to ten percent, compared with around a third after needle drainage alone. It is a short day-surgery procedure, taking around thirty minutes, under a regional or general anaesthetic. For some ganglions on the back of the wrist, keyhole surgery is an option, which avoids a visible scar. The wound is covered with a soft dressing. You can use the hand for light tasks within days, and the dressing comes off at around one week. Heavy gripping and impact loading are held off for two to four weeks while the joint capsule heals. The wrist can feel a little tight for a few weeks as the scar softens, and this settles steadily. Most people are back to normal activity by three to four weeks. A small number of ganglions can return even after good surgery, but for most people the lump is gone for good.
What you're feeling
You may notice a small, fluid-filled lump on your wrist. This is a ganglion cyst. It often feels like a smooth bump under the skin. For many people, this lump causes no pain at all. However, some patients experience discomfort around the cyst. The pain is often most noticeable on the back of the wrist. It can also occur on the palm side.
The pain typically worsens when you move your wrist. Activities that require forceful bending of the wrist back tend to aggravate the cyst. You might feel increased pressure or aching after using your hand for tasks like typing, lifting, or playing sports. Some patients report that the pain is more intense at night or upon waking in the morning. This flare-up can make it difficult to rest comfortably.
Daily tasks may become challenging due to pain or stiffness. Simple actions like turning a doorknob, opening a jar, or pushing up from a chair can feel uncomfortable. If the cyst is on the palm side, it might press on nearby nerves. This can sometimes cause symptoms similar to trigger finger, where your finger catches or locks when you bend it. You may also notice reduced grip strength or a feeling of weakness in your hand.
It is important to know that symptoms can change over time. In children under 10 years old, these cysts often appear on the palm side of the wrist. In this age group, the majority of cysts resolve on their own within 12 to 18 months. For adults, the cyst may persist or grow larger with continued use. If you have preoperative pain around a dorsal wrist ganglion, you should be aware that residual pain after surgery is more likely in female patients. Understanding these patterns helps you and your surgeon decide on the best path forward for your specific situation.
What's actually happening
A ganglion is a fluid-filled sac that forms near your wrist joints or tendons. Think of it like a small water balloon that develops from the joint lining. The joint produces lubricating fluid to help your wrist move smoothly. Sometimes, this fluid leaks out or pushes through a weak spot in the joint capsule. It collects into a lump under the skin.
You might notice this lump on the back or the palm side of your wrist. It can feel firm or squishy. The lump itself is not cancerous. It is just trapped fluid. However, it can press on nearby nerves or tissues. This pressure is often what causes your pain or discomfort. You might feel a dull ache or sharp pain when you move your wrist, especially if you extend it backward.
The cause is not always clear. Some people have naturally looser joints, which makes them more prone to developing these lumps. Women are more likely to get them, particularly on the palm side of the wrist. In children, they often appear on the back of the wrist. The good news is that many of these lumps go away on their own, especially in younger patients. Your body may reabsorb the fluid over time.
If the lump does not resolve, it can persist for months. It may grow larger with activity and shrink with rest. The fluid inside is thick and sticky, similar to egg whites. This consistency helps the sac maintain its shape. Even if it is not painful, it can be unsightly or interfere with daily tasks. Understanding that this is a mechanical issue with joint fluid helps explain why simple rest or splinting often helps. It gives the joint time to settle and may allow the leak to seal itself naturally.
What we can do about it
At Mater Private Hospital Rockhampton, Dr Kieran Hirpara approaches wrist ganglia by matching the treatment to your specific symptoms and lifestyle. We start with the least invasive options and move to surgery only if needed. Most ganglions are harmless, but they can cause pain or limit movement. We will discuss the best path for you based on what matters most in your daily life.
For many people, simple self-care is enough. If you have a ganglion on the front of your wrist, especially if you are a child under 10, we often recommend watchful waiting. In children, 69% to 79% of these cysts disappear on their own within 12 to 18 months. You can try changing your activities to avoid positions that strain the wrist, such as forceful extension. We may also suggest splinting to keep your wrist steady and resting. Physiotherapy can help strengthen the surrounding muscles and improve your range of motion. This approach aims to reduce irritation and allow the body to resolve the cyst naturally.
If self-care does not bring enough relief, we may discuss medical management. This usually involves pain medication or anti-inflammatory drugs to manage discomfort. We do not routinely recommend wrist X-rays for every patient, as they rarely change the treatment plan for a typical ganglion. In some cases, we might suggest an MRI scan to get a clearer picture of the cyst and surrounding tissues, which is accurate in 83% of cases. While some clinics offer injections, we advise against using sclerosant chemicals due to serious risks like artery injury. If you are experiencing significant pain, particularly if you are female with preoperative pain, we will discuss whether an injection or other non-surgical measures might help, keeping in mind that residual pain can still occur after any intervention.
Surgery is considered when conservative care has not worked, or if the ganglion is causing persistent problems. We recommend surgical excision for pediatric ganglions that remain symptomatic after about 2 months of observation or splinting. For adults, surgery is an option if the cyst causes ongoing pain or limits your function. Surgical removal significantly reduces symptoms and has a low chance of the cyst coming back. We offer both open and arthroscopic (keyhole) techniques. Open excision has a lower recurrence rate than arthroscopic methods, but it requires careful consideration if your job involves forceful wrist movements, as this can increase the risk of residual pain. We will help you weigh these options to make a shared decision that fits your recovery goals.
What to expect
Your wrist ganglion is a fluid-filled sac that often causes a visible lump and sometimes pain. For many people, this condition follows a slow, unpredictable course. About 40% of these lesions decrease in size over the first 6 years after you see a hand surgeon. In children under 10 years old, the outlook is even more positive. Between 69% and 79% of these lumps disappear on their own within 12 to 18 months. We often recommend watching and waiting or using a splint for young patients, as this helps the majority resolve without intervention.
If you choose not to treat the ganglion, it may stay the same, shrink, or occasionally grow. Aspiration, which involves draining the fluid with a needle, is an option but has a high chance of the lump returning. Most ganglions come back after this procedure. Surgical removal offers a significantly lower chance of recurrence compared to aspiration. Surgical excision of primary wrist ganglia significantly reduces patient symptoms with low recurrence rates and high patient satisfaction. The overall recurrence rate after surgery is about 10%.
Recovery feels different depending on the treatment path. If you have open surgical excision, you can expect a scar and a period of healing. Some patients experience residual pain or functional limitations, especially if your job or hobbies require forceful wrist extension. Female patients who have preoperative pain around dorsal wrist ganglia were the most likely to have residual pain after surgery. Arthroscopic surgery is another safe option supported by outcomes data up to 4 years. It avoids large scars but has a slightly higher recurrence rate than open excision.
We advise against using sclerosant injections to treat wrist ganglions. This practice must be abandoned due to the risk of catastrophic complications such as radial artery injury. Your surgeon will help you weigh these risks and benefits. The goal is to reduce your pain and improve your wrist function while keeping the risk of the lump returning as low as possible.
When to see someone
See your GP if you notice a lump on your wrist that causes persistent pain not improving with rest. Ask for a specialist review if you experience weakness, instability, or locking. Symptoms that interfere with sleep or work also warrant assessment. Sudden worsening of pain or swelling requires prompt attention. While many ganglions resolve on their own, especially in children, ongoing discomfort should not be ignored. Your surgeon can evaluate your specific situation to determine if further treatment is needed.
