Ganglions are cysts that form at a joint or on a tendon. The most common locations for ganglions are the front of the wrist, back of the wrist, and the joints at the tips of the fingers (also called mucous cyst). Ganglion cysts are usually filled with a clear, jelly-like fluid. They tend to get bigger in size depending on activity level. Ganglion cysts are usually not painful, but can cause soreness or irritation to the surrounding tissues as they get bigger;
