Ganglion cysts are benign masses that occur most frequently adjacent to the tendons of the wrist or hand. They are fluid-filled sacs that grow out of a joint, like a little balloon. Sometimes they appear suddenly, sometimes gradually. The ones that grow at the wrist tend to be larger and more noticeable; smaller ganglions can remain hidden under the skin.

Pain is not always a symptom of ganglion cysts, although it can be, since they can put pressure on the nerves. They may grow or shrink in size, depending on activity, or even disappear altogether on their own. It is frequently the small, hidden ganglions that cause more discomfort. The larger ones, whether painful or not, may be unsightly.

Care of the hand requires specialized attention because of its complexity. Dr. Cohen advocates a conservative, non-surgical approach whenever possible. Ganglion cysts frequently respond well to non-surgical treatments, which may include immobilization, medication, and aspiration (removal of the fluid). Dr. Cohen will determine the best course after a thorough examination. Sometimes, surgery is required.
