How is it caused?Ganglion cysts develop from the accumulation of fluid within the sac. There is no definite cause of a ganglion cyst but it is thought to be linked to injury – both acute trauma and repetitive stress over time.
What are the symptoms?While some cysts may remain asymptomatic, symptoms may include:
- Visible lump
- Discomfort when wearing shoes that press on the lump
- Numbness, tingling or pins and needles when a cyst presses on a nearby nerve
