Ganglion Cyst

What is a Ganglion Cyst?
A ganglion cyst is a fluid-filled swelling that develops near joints or tendons, most commonly on the wrist, hand, or fingers. It is benign (non-cancerous), but can be uncomfortable, restrict movement, or affect function.
​
Symptoms may include:
​
-
A visible lump near a joint
​
-
Pain, especially with movement or pressure
​
-
Weakness or reduced mobility in the affected joint

When Should I Seek Treatment?
​
You should consider treatment if:
​
-
The cyst is painful or restricts movement
​
-
It is growing or changing shape
​
-
It affects your grip or fine hand control
​
-
It has not responded to aspiration or conservative treatment

Can It Be Treated Without Surgery?
Yes. Non-surgical options include:
​
-
Observation: Some ganglions go away on their own
​
-
Aspiration: Removing the fluid with a needle
However, ganglions often return after aspiration.

What is Ganglion Excision Surgery?
Ganglion excision is a minor surgical procedure, done under local anaesthetic, to remove the cyst along with its root from the joint or tendon sheath to reduce recurrence risk.

What to Expect Before and After Surgery
Before Surgery:
​

Infection
​
-
Recurrence (can still happen in ~10–20% of cases)
​
-
Stiffness or scar sensitivity
​
-
Injury to nearby nerves or tendons (rare)

How Do I Prepare?
