A ganglion cyst is a tumor or swelling on top of the covering of a tendon or joint in the hand or wrist. The tendon is the tissue that connects your muscle with your bone. The cyst looks like a sac filled with a sticky, clear, colorless material. The size can vary, and larger cysts can feel firm or spongy.
These cysts may change in size or disappear spontaneously overtime. They may or may not also be painful. If they are painful, there are medications and surgical options that Dr. Lin and Dr. Cohen-Kashi can discuss with you.
