A wrist ganglion, or synovial cyst, is a “fluid-filled lump that commonly appears on the back or front of the wrist.” Though harmless, it can “cause discomfort or interfere with joint movement.”**Why does a wrist ganglion appear?**
Synovial fluid may build up due to repetitive wrist use, injuries, arthritis, or genetics. “Activities such as writing, typing, or playing sports can put stress on the joint,” while “a blow or sprain to the wrist can trigger the cyst’s formation.”

**Symptoms**
Ganglions “vary in size and can grow or shrink over time.” Common signs are a “visible, soft lump on the wrist,” pain during movement, or “a feeling of pressure or numbness if the ganglion presses on a nerve.”
**Treatments**
Options depend on severity. If painless, doctors often suggest observation: “doing nothing and just observing.” Immobilization with a brace can “reduce pressure on the joint.” Aspiration drains fluid but “there is a chance the cyst could recur.” Surgery is for severe cases and has a “lower chance of recurrence.”
**Conclusion**
A wrist ganglion is benign, but if bothersome, “consulting a doctor is essential to determine the best option.”
