If the cyst does hurt, apply ice 20 to 30 minutes three or four times a day and use anti-inflammatory medication. The fluid can be removed with a needle, although cysts often fill up again. Do not try to flatten the cyst by hitting it with a heavy object because even if it flattens, the cyst will almost always fill up again with fluid and hitting the cyst often damages the hand or wrist. Painful or unsightly cysts may be removed by surgery. Such surgery can be performed on an outpatient basis.
Healing is usually rapid and leaves only a small scar.
Ganglion cysts cannot be prevented. If you do have a cyst, avoid any activity that causes pain. If your work or leisure activity requires movement of your wrist in a repetitive fashion, wrist braces or taping of your wrist may be beneficial. As always, see your physician for a full evaluation of any health problem.
