What Is a Ganglion Cyst?
A ganglion cyst is a sac filled with a jellylike fluid that originates from a tendon sheath or joint capsule. The word “ganglion” means “knot” and is used to describe the knot-like mass or lump that forms below the surface of the skin.
Ganglion cysts are among the most common benign soft-tissue masses. Although they most often occur on the wrist, they also frequently develop on the foot – usually on the top, but elsewhere as well. Ganglion cysts vary in size, may get smaller and larger, and may even disappear completely, only to return later.
Although the exact cause of ganglion cysts is unknown, they may arise from trauma – whether a single event or repetitive micro-trauma.
A ganglion cyst is associated with one or more of the following symptoms:
- A noticeable lump – often this is the only symptom experienced
- Tingling or burning, if the cyst is touching a nerve
- Dull pain or ache – which may indicate the cyst is pressing against a tendon or joint
- Difficulty wearing shoes due to irritation between the lump and the shoe
To diagnose a ganglion cyst, the foot and ankle surgeon will perform a thorough examination of the foot. The lump will be visually apparent and, when pressed in a certain way, it should move freely underneath the skin. Sometimes the surgeon will shine a light through the cyst or remove a small amount of fluid from the cyst for evaluation. Your doctor may take an x-ray, and in some cases additional imaging studies may be ordered.
There are various options for treating a ganglion cyst on the foot:
- Monitoring, but no treatment. If the cyst causes no pain and does not interfere with walking, the surgeon may decide it is best to carefully watch the cyst over a period of time.
- Shoe modifications. Wearing shoes that do not rub the cyst or cause irritation may be advised. In addition, placing a pad inside the shoe may help reduce pressure against the cyst.
- Aspiration and injection. This technique involves draining the fluid and then injecting a steroid medication into the mass. More than one session may be needed. Although this approach is successful in some cases, in many others the cyst returns.
When is Surgery Needed?
When other treatment options fail or are not appropriate, the cyst may need to be surgically removed. While the recurrence rate associated with surgery is much lower than that experienced with aspiration and injection therapy, there are nevertheless cases in which the ganglion cyst returns.

TeleHealth and Tele-Visits in the time of COVID-19
Step Ahead Foot & Ankle Clinic, PC has initiated a TeleHealth Service during the COVID-19 Pandemic for a number of reasons:
1.) Our top priority has always been, and continues to be, Patient, Employee, Community Health and Safety.
2.) With the primary goal of triaging, or prioritizing what's urgent and what's not, Dr. Barnes seeks to help patients with the foot concerns over the phone or computer. Caring for patients in this way, and arranging for visits in clinic if necessary (infections, ulcerations, injuries) and in a controlled environment, she hopes to do her part in allowing to the Urgent Cares and Emergencies Rooms help those with needs related to the virus.
3.) Although Dr. Barnes obviously cannot physicially treat you or other patients over the phone or computer, she can hopefully see if your concern would be best treated physically, and arrange for this to be done. If she can help give you direction and advice over the computer or phone, she will do so. This particularly applies to you if you have foot pain, as many treatment options can be relayed in this way (stretches, shoe recommendations, orthotic recommendations).
4.) During this time of anxiety, stress, and uncertainty, Dr. Barnes wants to do her part in helping you do the things you need to do (caring for a loved one, running outside for stress relief, or walking on a treadmill at home, for example) without foot pain interfering. She does't want you to have to wait months or an indefinite period of time for you to get back on your feet! "CLICK HERE TO REQUEST A TELEVISIT."
