A ganglion is a lump under your skin that contains fluid.
Most ganglions form near the wrist (see figure 1). They are also found on your ankle and foot. The fluid in the ganglion comes from a joint or tendon through a narrow channel.
The lump and any discomfort from it should settle. Surgery gives the best chance of preventing the ganglion from coming back.
A ganglion will often settle after a year or two. If your ganglion is not causing much trouble it is best to leave it alone.
The fluid can be taken out of the ganglion using a needle. This improves any discomfort for a while. Your doctor may also inject the ganglion with a steroid (cortisone). These treatments may help for a short time.
Various anaesthetic techniques are possible. The operation usually takes 15 to 30 minutes.
Your surgeon will make a cut over the ganglion and separate the ganglion from the nearby tendons, nerves and blood vessels. They will remove the ganglion.
You should be able to go home the same day.
Regular exercise should help you to return to normal activities as soon as possible. Before you start exercising, ask the healthcare team or your GP for advice.
The joint where the ganglion was can continue to ache but any joint stiffness should settle quickly.
Some ganglions come back after a few months or years.
A ganglion is not serious. If it is causing trouble, your surgeon can remove it.
