What Exactly is a Ganglion Cyst?

dupuytrens fitzmaurice hand instituteGanglion cysts are benign (non-cancerous) growths that may be painful when proximity to a nerve results in pressure on the nerve. Depending on where the cyst is located, it may affect and interfere with the mobility and flexibility of the joint.

Signs and Symptoms of Ganglion Cysts

While most ganglion cysts tend to be painless, some cysts can develop near the site of a nerve, causing:

  • Pain
  • Numbness
  • Tingling
  • Muscle fatigue

The most common site for ganglion cysts is along the joints and tendons of the hands and wrists. They can also be fairly common along the joints of the feet, but can also occur along other joints in the body as well.

Causes and Risk Factors For Ganglion Cysts

A direct cause for the development of a ganglion cyst is unclear. They can develop along a joint, or along the lining of a tendon, and are composed of fluid similar to the fluid that lubricates the joints and tendons.

Factors that may increase the risk of developing a ganglion cyst include:

Age and gender – While ganglion cysts can develop in anyone, they are most common in women between the ages of 20 and 30.

Osteoarthritis – People suffering from wear-and-tear arthritis in the hands run a higher risk of developing ganglion cysts in the finger joints near the tip of the fingers.

Joint or tendon injury – Previously injured joints or tendons have a higher risk of developing a ganglion cyst at some point in the future.

Treatment for Ganglion Cysts

Treatment options for a ganglion cyst will depend on the size, location, and accompanying symptoms. If the cyst is causing pain or affecting joint function, board-certified hand surgeon Dr. Michael Fitzmaurice of the Fitzmaurice Hand Institute in Phoenix might recommend draining the cyst of fluid or surgical removal of the cyst.
