What Causes a Ganglion Cyst on Top of Foot? Understanding Symptoms and Seeking Effective Treatments

Dealing with a ganglion cyst on top of foot can be perplexing. These fluid-filled lumps are generally benign but knowing when to seek treatment is crucial. This article demystifies foot ganglion cysts by outlining key symptoms, exploring their common causes, and discussing effective treatment options to manage any discomfort and prevent complications.

What is Ganglion Cysts on the Foot: A Comprehensive Overview

A ganglion cyst, also known as a ganglion, is a knot-like mass filled with a jellylike fluid. It typically originates from a tendon sheath or joint capsule. The term ‘ganglion’ perfectly describes this condition, as it means ‘knot’. While ganglion cysts most commonly develop on the wrist, forming wrist ganglia, they are also frequently seen on the foot, specifically in areas such as the ankle care.

On the dorsal foot, ganglion cysts commonly appear in the following areas:

• Over the talus to the navicular
• The cuneiform to the metatarsus
• Solely the cuneiform
• The area involving both the talus and the cuneiform-metatarsus

These lumps, also known as soft tissue masses, while often painless, can become a source of discomfort due to their size or location.

Identifying Ganglion Cyst Symptoms

Identifying a ganglion cyst involves recognizing certain tell-tale signs. These fluid-filled sacs typically form on the top of the forefoot or midfoot and around the ankle, presenting as foot lumps, specifically a soft, noticeable lump.

When Pain Becomes Noticeable

The pain associated with a ganglion cyst can vary, and it often becomes noticeable when the cyst exerts pressure on a ligament or tendon. This discomfort is not limited to a dull ache; individuals may also experience a tingling or burning sensation, or even a throbbing pain.

The location of the cyst plays a significant role in the intensity of the pain. For instance, a ganglion cyst on the dorsal foot can cause heightened discomfort due to its proximity to thin subcutaneous tissue over the foot bone, or when it is close to an artery or nerve.

Variability in Size and Discomfort

Ganglion cysts are not static in size. They can enlarge, shrink, or even resolve entirely without intervention. The spectrum of size variability is quite extensive, with the smallest cysts being the size of a pea and the average width of cysts on the dorsal foot reaching approximately 2.9 cm.

The size of the cyst can significantly affect the level of discomfort experienced. Larger cysts can potentially lead to increased discomfort, especially when they exert pressure on nearby nerves. To decrease pain, it is essential to address the underlying cause of the cyst.

The Root Causes of Foot Ganglion Cysts

Ganglion cysts often develop due to wear shoes and tear on tendons or joints, possibly resulting from a single event or repeated injuries, including tendon injury. Other factors, such as bone spurs or joint and tendon damage due to arthritis, can also lead to the formation of these cysts. Understanding what causes ganglion cysts can help in their prevention and recommend treatment.

Despite these identifiable contributing factors, the exact cause of ganglion cysts remains unclear. They typically contain thick fluid and grow out of a joint or tendon lining. The bulging of the joint tissue stemming from flaws in the joint capsule or tendon sheath is also associated with the development of ganglion cysts.

The Intersection of Ganglion Cysts and Footwear

Ganglion cysts on the foot can lead to irritation or causing pain when wearing shoes, as they apply pressure on the cyst or when the cyst exerts pressure on nearby nerves. Therefore, it’s important to choose footwear that can accommodate the cyst and reduce the pressure exerted on it.

Shoes recognized by the American Podiatric Medical Association, such as those from Chaco, provide good arch support and adjustable straps to alleviate pressure on ganglion cysts. Other brands like:

• Hoka One One
• New Balance
• ABEO
• Brooks
• Ecco
• ASICS

and others offer specialized features such as extra cushioning, stability, and space for custom orthotics, which are beneficial for those with foot conditions including ganglion cysts and soft tissue concerns.

Treatment Options for Ganglion Cyst on top of Foot: From Aspiration to Surgery

Ganglion cysts can often be managed with non-surgical treatments. These include monitoring the cyst’s condition, aspiration to drain the cyst’s fluid, and using steroid medication to reduce inflammation.

However, in cases where the cyst causes persistent or severe pain and other treatments are unsuccessful, surgical removal—known as excision—may be necessary.

Why Monitoring May Be Enough

For non-painful ganglion cysts, immediate intervention may not be necessary. Instead, a healthcare provider might suggest observing the cyst for changes over time.

The Role of Steroid Medication

Steroid injections form one of the treatment options for managing ganglion cysts on the foot. The medication helps shrink the remainder of the cyst following other treatment methods.

After the initial aspiration of a ganglion cyst, a doctor may inject the cyst with a steroid medication to further reduce its size. However, it’s important to note that all treatments come with potential risks, such as infection, injury to adjacent structures, scarring, and recurrence of the cyst.

Recurrence and Long-Term Management

The recurrence rate of ganglion cysts after treatment varies and is influenced by factors such as cyst size, location, and the method of treatment. Surgical treatments demonstrate a significantly lower recurrence rate of around 6%, compared to rates experienced with aspiration and injection therapy.

Long-term management strategies for ganglion cysts might include:

• Using a brace or splint to immobilize the joint
• Reducing activities that could cause the cyst to grow
• Periodic drainage if the cyst recurs and causes discomfort

However, patients are strongly advised against employing self-treatment methods due to the risks of injury and infection, and should instead consider an outpatient procedure as a part of their treatment strategy.
