A ganglion is a cyst that can be found in different areas of the wrist or fingers. They are filled with mucus-like fluid, similar to what is found in the joint. They are often harmless and disappear on their own. In some cases they can cause soreness.
There is no clear trigger for ganglia. They are common in gymnasts who experience repeated stress to the wrist.
To receive a diagnosis, a qualified musculoskeletal expert will first take a medical history and conduct a physical exam. MRI testing may also be ordered.
Initial treatment is non-surgical. Observation, immobilization, aspiration, and cortisone injection are first treatment options. If needed, surgery can be used to remove the ganglion.
