How do you get ganglion cyst?

A ganglion cyst is a fluid-filled sac that develops on the back of the wrist or hand. It is caused by a weakness in the joint capsule or tendon sheath, which allows synovial fluid to leak out and form a cyst.

Some factors that can increase the risk of developing a ganglion cyst include:

* Repetitive motion: Activities that involve repetitive wrist or hand movements, such as typing, writing, or playing a musical instrument, can increase the risk of ganglion cyst formation.

* Wrist injury: A ganglion cyst can also develop after a wrist injury, such as a sprain or fracture.

* Certain medical conditions: Some medical conditions, such as osteoarthritis and rheumatoid arthritis, can increase the risk of developing a ganglion cyst.

Ganglion cysts are usually not painful, but they can sometimes cause discomfort or interfere with movement. If you have a ganglion cyst that is causing you pain or discomfort, your doctor may recommend treatment options such as aspiration, surgery, or corticosteroid injections.
