Ganglion Cyst

Small, jelly-like bumps called ganglion cysts are common in the wrists, hands, ankles, and feet. These cysts are typically round or oval and filled with a fluid similar to jelly. They're not cancerous. Sometimes, these cysts are as small as a pea, but they can change in size.

Ganglion cysts are usually harmless, but they can cause problems if they press on nearby nerves or joints. This pressure can lead to pain and limit movement.

If a ganglion cyst is causing discomfort, a doctor might drain it with a needle, or surgery to remove it could be an option. However, if a cyst isn't causing any problems, no treatment is needed. Many cysts will grow and shrink over time, and some even disappear on their own.

Ganglion cysts are common, often harmless bumps that develop near joints, especially in the wrists, hands, ankles, and feet. They're typically smooth and round or oval-shaped, though some are so small you can't feel them. Sometimes, these cysts grow larger, especially when you move the affected joint.

Most ganglion cysts don't cause pain. However, if a cyst gets big enough, it might press on nearby nerves or tissues. This can lead to pain, tingling, numbness, or even muscle weakness. If you notice a swelling or lump, or experience pain in your wrist, hand, ankle, or foot, it's a good idea to see a doctor. They can properly diagnose the problem and recommend the best course of action, which might include treatment.

If you feel a lump or experience pain in your wrist, hand, ankle, or foot, it's important to see a doctor. A healthcare professional can examine you, figure out what's causing the problem, and determine if treatment is necessary. This will help you understand the issue and get the best possible care.

Ganglion cysts are mysterious bumps that can appear on joints or the coverings of tendons. They're sort of like tiny, fluid-filled sacs, resembling a water balloon on a small stem. The fluid inside is similar to the lubricating fluid you find in joints or around tendons. Doctors don't fully understand what causes these cysts to form.

Ganglion cysts can happen to anyone, but some factors increase the chances.

Who's more likely to get one?

• Mostly women in their 20s and 40s: While anyone can get a ganglion cyst, these growths are more common in women within this age range.

• People with osteoarthritis: Osteoarthritis, a type of arthritis where the cartilage in joints wears down, specifically in the joints closest to the fingertips, can raise the risk of ganglion cysts forming near those areas. This is because the worn-down cartilage and inflammation can weaken the tissues, making them more susceptible to the cyst formation.

• Past joint or tendon injuries: If you've had an injury to a joint or tendon, that area is more prone to developing a ganglion cyst. This is because the injury can weaken the tissues and create a place where the cyst can develop. Even a minor injury can increase risk.

A healthcare professional might gently press on a cyst during a physical exam to check for pain. They might also shine a light through it to see if it's solid or contains liquid. Tests like X-rays, ultrasounds, or MRIs can help figure out what's going on and rule out other possibilities, such as joint pain (arthritis) or a growth (tumor). Sometimes, a small amount of fluid is taken from the cyst using a needle. This sample can help confirm the diagnosis. For example, fluid from a ganglion cyst is usually thick and clear.

Mayo Clinic offers different imaging services including MRIs, ultrasounds, and X-rays for diagnosing and managing ganglion cysts.

Ganglion cysts are often harmless bumps that usually don't cause pain. In most cases, no treatment is needed. Your doctor might just want to monitor the cyst to see if it changes.

However, if the cyst is painful or interferes with movement in a joint, there are a few options:

• Rest and Immobilization: Keeping the affected joint still can help. A brace or splint might be recommended to limit movement. This can help the cyst shrink and reduce pressure on nearby nerves, easing pain. But using a brace or splint for a long time could weaken the muscles around the joint.

• Drainage: A doctor can use a needle to drain the fluid inside the cyst. However, the cyst might come back.

• Surgery: If other methods don't work, surgery might be an option. The procedure removes the cyst and the small part connecting it to the joint or tendon. While this is usually successful, there's a small risk of injuring nearby nerves, blood vessels, or tendons. Even after surgery, the cyst could potentially return.

Important Considerations:

In most cases, ganglion cysts are not serious and resolve on their own. If you have concerns about a ganglion cyst, it's crucial to talk to your doctor. They can evaluate your specific situation and recommend the best course of action.
