Ganglion Cyst Treatment in Boise

Ganglion cysts are fluid-filled lumps that commonly develop along the joints or tendons of the wrist or hand. While these cysts are noncancerous, they can cause pain, discomfort, or limit movement if they press on nearby nerves or structures. At Idaho Hand Center, we provide thorough evaluation and treatment to relieve symptoms and restore normal hand and wrist function

What Is a Ganglion Cyst?

A ganglion cyst forms when fluid leaks from a joint or tendon sheath and collects in a small sac. These cysts often appear on the back of the wrist, the palm side near the thumb, or at the base of the fingers.

Ganglion cysts can vary, sometimes growing larger with activity and shrinking at rest. Common symptoms include:

A visible lump under the skin
Aching or localized pain, especially with movement
Tingling, numbness, or weakness if the cyst presses on a nerve
Stiffness or reduced range of motion in the affected joint

The exact cause is unknown, but repetitive wrist movements, previous injuries, or joint conditions like arthritis may increase the risk.

How Are Ganglion Cysts Diagnosed?

At Idaho Hand Center, diagnosis begins with a physical examination to assess the cyst’s location, size, and firmness. We may use:

Transillumination (shining a light through the cyst) to confirm it is fluid-filled
Ultrasound to differentiate a cyst from other masses and check for solid tissue
MRI in rare cases to evaluate deeper or more complex cysts

Most ganglion cysts are harmless, but we recommend evaluation if the lump causes discomfort or limits function.

What Are the Treatment Options for Ganglion Cysts?

Many ganglion cysts are painless and may resolve on their own without treatment. When intervention is needed, options include:

Observation for cysts that are small and asymptomatic
Wrist splinting to limit movement and reduce irritation
Aspiration to drain fluid from the cyst (though recurrence is possible
Corticosteroid injection after aspiration to help prevent regrowth
Surgical excision to remove the cyst and its stalk, reducing the risk of recurrence

We tailor treatment to your symptoms, activity level, and preferences to achieve the best outcome.

When Should You See a Hand Specialist?

Seek evaluation if a lump on your hand or wrist is painful, interferes with movement, or changes in size. Early assessment at Idaho Hand Center ensures accurate diagnosis and allows us to recommend the most effective treatment plan.
