Ganglion Cyst
Ganglion cysts are the most common benign soft tissue masses in the hand and wrist. They are fluid-filled sacs that arise from joint capsules or tendon sheaths, forming a smooth, round lump just under the skin. The back of the wrist accounts for about 60–70% of cases. They can also appear on the palm side of the wrist, at the base of fingers, or on the foot. Their size fluctuates—some swell with activity and shrink with rest.

Symptoms
- A visible, round, smooth lump under the skin near a joint or tendon
- The lump is firm or rubbery and may feel slightly movable
- Size that changes over time—often larger with activity, smaller at rest
- Aching or dull pain, especially after repetitive use of the wrist or hand
- Numbness or tingling if the cyst presses on a nearby nerve
- No pain in many cases—often noticed incidentally
When to See a Doctor
See a hand surgeon if a lump near your wrist or hand is growing, causing persistent pain, or producing numbness or weakness. While ganglion cysts are benign, other masses can look similar—any new lump near a joint deserves evaluation. A cyst on the palm side of the wrist near the pulse point (the radial artery) should not be aspirated without imaging first.
Treatment Options
Observation ("watch and wait")
Up to 40–60% of ganglion cysts resolve on their own. If the cyst is not painful and not causing functional problems, doing nothing is a completely reasonable approach.
Aspiration
The cyst is drained with a needle in the office under local anesthetic. Quick and effective short-term, but recurrence rates are around 50%, since the root connection to the joint is not removed.
Surgical excision
The cyst and its root stalk are removed arthroscopically or through a small incision. Lower recurrence rate than aspiration (around 5–15%). Recommended for cysts causing persistent pain, functional limitation, or recurring after aspiration.
Recovery Timeline
Aspiration: same-day procedure, no recovery downtime, but cyst may return over weeks to months. Surgical excision: return to light activity in 2–3 weeks, full wrist strength and range of motion restored in 4–8 weeks. Recurrence after surgery is uncommon.
Frequently Asked Questions
Will hitting a ganglion cyst with a Bible make it go away?
The old "Bible therapy" involved slamming a heavy book onto the cyst to rupture it. It sometimes worked, but also sometimes caused pain and swelling, and the cyst often came back anyway. Modern aspiration accomplishes the same result more safely and without the bruising. Most orthopaedic surgeons advise against self-treatment.
Are ganglion cysts dangerous?
Ganglion cysts are benign—they are not cancerous and do not spread. The main concerns are pain with activity, cosmetic appearance, and rarely nerve compression causing numbness. They do not transform into anything harmful. The main reason to treat them is discomfort, not medical necessity.
What type of doctor treats ganglion cysts?
Hand surgeons and orthopaedic surgeons who specialize in the hand and wrist treat ganglion cysts. Simple aspiration can often be done in a primary care or urgent care setting as well.
