What Is a Ganglion Cyst?
A ganglion cyst is a mass of tissue that is filled with a jellylike fluid. The word “ganglion” means “knot” and is used to describe the knot-like mass or lump of cells that forms below the surface of the skin.
Signs and Symptoms
A ganglion cyst is associated with one or more of the following signs and 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.
