Recognising the Symptoms and Signs

Ali Phillips | Hand & Wrist Specialist
I'm Ali Phillips. Finding a new lump can be unsettling, but it's often something harmless. I'm here to provide clear, kind, and trustworthy information to help you understand what it might be and what we can do about it.
Book a ConsultationA ganglion cyst is a very common, non-cancerous lump that often appears on the hands and wrists. Think of it like a small, smooth balloon filled with a thick, jelly-like fluid, connected to a nearby joint or the sheath that covers a tendon.
The exact cause is unknown, but they might form due to irritation or small leaks from a joint. They can appear suddenly, change in size, and sometimes even disappear on their own. While they are harmless, they can sometimes cause discomfort.
The most obvious sign is a soft, round, and smooth lump under the skin, most commonly on the back of the wrist.
While many are painless, a cyst can ache or cause discomfort, especially if it presses on a nearby nerve.
Depending on its size and location, a cyst can sometimes interfere with joint movement or make gripping difficult.
If you have a lump that's causing you pain or limiting your activities, you don't have to just live with it. An accurate diagnosis is the first step towards peace of mind. Let's talk about your options.
Get a Clear DiagnosisMaria, a 35-year-old graphic designer, developed a noticeable lump on the back of her wrist. At first, it didn't bother her, but over a few months, it began to ache, especially after a long day of using her computer mouse. She was worried it might affect her work. After we talked, she was relieved to learn it was a harmless ganglion. We decided to simply observe it for now, and I gave her advice on ergonomic adjustments to ease the strain on her wrist.
Tom, a keen guitarist, noticed a small, hard lump at the base of his finger on his palm. It was a 'seed ganglion' and it was exquisitely tender, making it painful to press down on the guitar strings. It was small, but it was having a big impact on his passion. After non-surgical options didn't provide enough relief, Tom opted for a minor surgical procedure to remove the cyst. The recovery was quick, and he was thrilled to be back to playing his guitar comfortably within a few weeks.
Getting the right diagnosis is key. When you see me, the process is usually very straightforward:
Listening to Your Story: First, I'll listen to you describe the lump, when you noticed it, and any symptoms it's causing.
A Gentle Examination: I will carefully examine the lump, checking its size, shape, and firmness. I might also press on it to see if it's tender or moves.
Using Technology (If Needed): In some cases, especially to confirm the diagnosis or rule out other issues, an ultrasound scan can be very helpful to see the fluid inside the cyst and where it's coming from.
In most cases, a physical examination is all that is needed to confidently diagnose a ganglion cyst and discuss the next steps with you.
Worrying about a lump is worse than knowing what it is. A simple consultation can provide clarity and a clear path forward. Let's get you the answers you need.
Book Your AppointmentTreatment is only needed if the cyst is painful or limits your movement. Many cause no trouble and can be left alone.
Surgery is considered when non-surgical options fail, or if the cyst is causing significant pain or interfering with your daily life.
The procedure is called a ganglion excision. I make a small incision over the lump and carefully remove the entire cyst, including its "stalk" where it connects to the joint or tendon. This is usually a quick procedure done under local anaesthetic, and recovery is generally fast.
The decision to have surgery is one we make together. I will ensure all your questions are answered so you feel confident in our plan.
If we decide surgery is the right path, it is imperative that you understand the process, the risks, and your rights. This is a partnership, and your informed consent is the most important part.
You have every right to choose not to have surgery. Small, painless ganglions often disappear on their own, so observation is a perfectly valid option. We can always explore other treatments or decide on no treatment at this time. The decision is yours.
It is critical to appreciate that all surgery has risks. The decision to proceed is a fine balance between the potential benefits and these risks.
The only person who can judge that balance is you. My role is to give you the clearest possible information so you can make the choice that is right for you.
Surgery for ganglion cysts is generally very safe. However, I want you to be aware of the potential issues. Potential issues include:

Yes, it's quite common for ganglion cysts to disappear spontaneously without any treatment at all. This is why observation is often the first recommendation if the cyst isn't causing any problems.
No, ganglion cysts are always benign, which means they are non-cancerous. While any new lump should be checked by a doctor, you can be reassured that these cysts are not malignant.
No, you should never try to pop or burst a ganglion cyst yourself. The historical "bible thump" method is not recommended as it can damage the surrounding tissues and lead to infection without effectively treating the cyst.
When a cyst is drained (aspirated), only the fluid is removed. The small hole in the joint lining and the outer wall of the cyst remain, so it's very common for the fluid to build up again over time. Surgical removal of the entire cyst structure has a much lower rate of recurrence.
Recovery is usually quite quick. You'll likely have some mild discomfort and a dressing for a few days to a couple of weeks. Most people can resume their normal activities within a few weeks of the procedure.
It is a non-cancerous, fluid-filled lump that often develops near joints or tendons, most commonly on the wrist.
The exact cause is unknown, but they may form due to irritation or mechanical stress on a joint or tendon. Fluid comes out of the joint through a tiny hole in the lining but it cannot get back in and so fills up. It squashes the tissues around it causing it to become like a ball. it forms a pseudo capsule but can disperse. It used to be treated by hitting them with a Bible because it was the heaviest book in the house!
Most noticeable symptom is a bump on the wrist or hand, though they can occur in other areas. They might be painful, especially if pressing on a nerve, and sometimes change in size. Many times, there are no other symptoms.
We commonly diagnose them through examination but sometimes imaging tests like ultrasound or MRI are used to confirm the diagnosis or rule out other causes.
Yes, they most often disappear spontaneously and require no treatment.
Treatment is only recommended if the cyst is painful, limits movement, or causes problems due to its appearance.
Observation: Many cysts cause no trouble and are simply monitored.
Immobilisation: A splint or brace can temporarily support the area, potentially decreasing its size and relieving pain.
Aspiration: Fluid inside the cyst is drained using a needle and syringe. This often provides temporary relief, but cysts invariably refill.
I clean the area, numb it with a local anaesthetic and then carefully insert a needle to withdraw the fluid. Steroid medication may be injected after aspiration. I do not perform this often as the cysts simply refill.
Surgery is considered when nonsurgical options fail to offer relief or cysts reoccur. It involves careful removal of the cyst and its stalk (which connects to a joint or tendon).
Think of the ultimate indication for surgery being “when the ganglion interferes with the joy in your life”!
Surgical removal is generally successful, but there’s a small risk of the cyst returning.
Risks include infection, bleeding, nerve or blood vessel damage, stiffness, and recurrence of the cyst.
Recovery usually takes a few weeks. Hand therapy might be recommended to aid recovery.
No, do not attempt to pop it yourself. This was once known as “bible thumping” and risks rupturing the cyst, potentially making it worse, and increasing the risk of infection.
Sometimes, applying a warm compress or soaking the area might offer temporary pain relief.
No, ganglion cysts are not contagious and don’t spread to other parts of your body.
Ganglion cysts are almost always benign (non-cancerous).
They are more common in women, especially between the ages of 20 and 40.
Your GP can usually diagnose and initially manage them. For cases requiring surgery, they may refer you to me but I need you to have tried leaving it alone and then some more leaving it alone and then I’ll consider taking it away!
Typically yes, exercise shouldn’t worsen it. Listen to your body and avoid activities that cause significant pain.
