Ganglia are thin walled cysts filled with clear fluid arising from joints or tendon sheaths. They grow on the top of the wrist (dorsal ganglions), underside of the wrist, at the end joint of a finger and occasionally affect the feet. 

Homeopathy does help in curing ganglions. It does so by reducing the size as well as by systemic re-absorption of the fluid from the ganglion. The results are long-lasting and usually permanent. Do however note that the outcome is better when treatment is started as early as possible and continued for a few months meant for the medicines to act.

The medicines prescribed are purely internal homeopathic medicines capable of softening the ganglion and then reabsorb the fluid from within. No external applications or corrective measure recommended.

There is no definite known cause that triggers the formation of the ganglion.

Large ganglia are usually visible and unattractive. Small ganglia that stay below the skin surface are usually painful. The pain may be localized in the wrist (dorsal ganglia) or may radiate to the arm & fingers.
