What are the symptoms of a ganglion cyst?
A ganglion cyst usually appears as a stationary, smooth bump from 1 to 3 centimeters in diameter. The cyst may disappear and reappear, may be soft or firm, and it may change size. Sometimes, a ganglion cyst will cause pain, aching, or numbness if it presses upon nerves. When attached to a tendon, the cyst can make the affected area feel weaker.
