About ganglion cysts

Ganglion cysts are fluid-filled sacs. They can occur at any joint in your body, but are most common around the wrist. Ganglion cysts may also appear on the feet.

Ganglion cysts form when the natural lubricating fluid leaks out of a joint or tendon, making a little sac (or cyst).
