A ganglion cyst is a common and harmless lump that often occurs on the wrist or fingers. It consists of synovial fluid that has collected in a small cyst and can sometimes cause tenderness or discomfort when strained. Here you will get a clear overview of what a ganglion is, why it occurs, what symptoms are common and how you can relieve the discomfort.
What is a ganglion cyst?
A ganglion cyst is a fluid-filled swelling that usually occurs over a joint or tendon, usually in the wrist or fingers, but can also occur on the dorsum of the foot. The lump consists of synovial fluid that has leaked through the joint capsule or tendon sheath, forming a soft or firm cyst-like lesion. A ganglion cyst is harmless and usually causes no discomfort, but it can be tender and painful.
Common causes & risk factors
The exact cause is not always known, but a ganglion cyst often occurs in connection with overuse or irritation of a joint or tendon. Repetitive movements, previous injuries or osteoarthritis of the small joints of the hand can contribute. People who work a lot with their hands or perform monotonous movements are at increased risk. Anyone can be affected. Ganglion cysts on the top of the wrist are most common in younger women who play sports.
Symptoms
Symptoms usually consist of a visible lump. It can vary in size over time. It may feel firm or soft to the touch. Sometimes there is pain, especially with strain or pressure on the area. Some people experience numbness or weakness if the ganglion presses on a nerve.
When should you seek medical attention?
You should seek medical attention if the lump grows, hurts, affects function, or if you are unsure of the diagnosis. Lumps that appear suddenly or change in appearance should be evaluated by a healthcare provider to rule out other conditions. The ganglion cyst can heal on its own.
Recommended protection & support
A wrist brace can relieve pressure on the wrist and reduce irritation around the ganglion cyst if it is placed at the wrist. By stabilizing the area, the brace can help reduce discomfort during activity. Avoid excessive strain and repetitive movements for a period of time to give the tissue a chance to recover.
