What is it?
A ganglion is a fluid-filled sac that grows from a joint or tendon sheath. It is the most common lump in the foot and ankle. Other lumps, such as fatty lumps (lipomas) and fibrous lumps, can also occur. Most lumps in the foot are harmless.
What causes it?
- Ganglions often have no clear cause, though they can follow minor injury or joint wear.
Common symptoms
- A lump that may change in size.
- Pressure or rubbing in shoes.
- Tingling if the lump presses on a nerve.
How is it diagnosed?
Diagnosis is by examination and usually an ultrasound or MRI scan. A sample (biopsy) is taken if there is any doubt about what the lump is.
Things you can do now
- Choose shoes that don't press on the lump
- Use padding around it
- Don't try to burst or drain it yourself
Treatment
Treatment is tailored to your individual needs, symptoms and goals. Depending on your situation, it may include monitoring, padding or a change of footwear, draining the lump with a needle (aspiration) and surgical removal.
Mr Jeyaseelan will talk you through the options that are right for you at your consultation.
When to see a specialist
- Any new lump in the foot or ankle, so it can be checked
- A lump is growing quickly, painful or larger than about 5cm
- A lump feels hard or fixed
What to expect
Most foot lumps are harmless. Ganglions often come and go and can be drained or removed if they cause problems. Any lump that is growing should always be assessed.
Please see a doctor about any lump that is growing quickly, painful at night or larger than a golf ball.
