A ganglion cyst is a harmless fluid-filled lump that usually appears near a joint.
Ganglion cysts feel like a smooth lump under your skin. They're most common on the wrists, hands and fingers.
A ganglion cyst often disappears on its own. If it’s causing discomfort, you can get it removed by having the cyst drained or cut out.
