What Are Ganglions? ...
A ganglion is a fluid-filled swelling of the lining of a joint or tendon. Although ganglions can form on any part of the foot, they most often appear on the ankle or top of the foot. Ganglions tend to change in size a usually grow slowly.
Causes: repeated irritation can weaken the lining of a joint or tendon and lead to ganglions. People who wear boots are more vulnerable to ganglions, as this type of footwear puts stress on the foot and ankle. Bone spurs (bony outgrowths) may also cause ganglions by irritating the joints and tendons.
Symptoms: Ganglions often form with no symptoms. But if the ganglion puts pressure on the nerves in the overlying skin, it can cause tingling, numbness, and pain. Ganglions sometimes swell and their size can change with different activities or a change in weather.
Because ganglions are sometimes mistaken for tumors, it's important to have a complete examination and possibly, test to confirm the diagnosis.
During your evaluation, your podiatrist may do a translumination exam, shining a light through the swelling (usually, you can see though a ganglion, but not though a tumor. When your foot is palpated (pressed), a ganglion feels spongy and the fluid moves from side to side.
If a ganglion is causing ongoing or severe pain your podiatrist may recommend surgery. The entire ganglion wall is removed during the
procedure: some surrounding tissue may also be removed.
After surgery you may feel pain, swelling, numbness, or tingling for several weeks following surgery. You'll probably be able to walk soon afterward, though your foot may need to be wrapped or in a cast. Be sure to see your podiatrist if you notice any problems in the future. Although surgery is usually successful, there is a chance that ganglion will occur.
