Cysts – Ganglion

Although the exact cause of ganglion cysts is unknown, it is theorized that they arise from trauma—either a single event or repetitive microtrauma. By definition, 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 vary in size, can get smaller and larger, and can even disappear completely, only to return later. Symptoms can include a noticeable lump on the foot, tingling or burning (if the cyst is touching a nerve), dull pain or ache (indicating the cyst is pressing against a tendon or joint), and difficulty wearing shoes due to irritation between the lump and the shoe. Treatment options include monitoring, shoe modifications, and aspiration or injection. If nonsurgical treatment is not effective, a surgical intervention may be warranted.

“Ganglion cysts are usually harmless. If they cause pain, difficulty moving the joint, or are just merely too unsightly, a doctor may remove them. Ganglion cysts mostly affect people age 15 to 40 years old and develop more often in females.”
