Ganglion cysts are fluid filled sacs that contain clear, mucus-like fluid that will occur at the capsule of a joint or the sheath of a tendon. They can be found at different places on the wrist. These cysts can be found on top of the wrist, on the underside of the wrist between the thumb and your pulse point, at the end joint of a finger, or at the base of a finger. (ganglionar)
The cause of a formation of a ganglion is unknown but typically occur more often in women and those who repeatedly apply stress to the wrist such as gymnasts.
Typically, ganglion cysts are non-painful and will often disappear in time. Usually, the more active the wrist, the larger the cyst becomes. With rest, the lump generally decreases in size.
It is possible that the ganglion cyst may put pressure on the nerves that pass through the joint therefore may be painful. Large cysts may not be painful but treatment may be chosen since they are considered unattractive.
There are several treatments for this problem from choosing to wait for the fluid to dissipate and improve on its own, draining (or aspirating) the swelling with a needle or surgically excising (removing) the cyst. It is possible that swelling can re-occur with any of these options.
It is important to discuss options with your surgeon further to determine what the best treatment is for your condition.
