Have you ever noticed a strange lump on your wrist that seems to appear out of nowhere? You’re not alone. Many people develop this type of lump, which is commonly known as a ganglion cyst. Surprisingly, it may be caused by everyday activities, especially those that put repetitive strain on your wrists.
What Is a Ganglion Cyst?
A ganglion cyst is a fluid-filled lump that usually forms near joints or tendons, commonly on the wrist, hands, ankles, or feet. These cysts are noncancerous and typically contain thick, jelly-like fluid. They can vary in size, sometimes getting bigger or smaller over time, and may cause discomfort or limit movement.
What Causes It?
While the exact cause of ganglion cysts remains unclear, research suggests that repetitive stress on joints and tendons can trigger their formation. Some common daily activities that might contribute include:
- Typing or using a mouse for extended periods
- Frequent texting or using a smartphone
- Repeated wrist movements in sports like tennis, golf, or weightlifting
- Manual labor involving gripping or twisting motions
Overuse of the wrist joint can lead to excess fluid production in the joint capsule or tendon sheath, which may then form a cyst.
Symptoms to Watch For
- A smooth, round lump near the wrist or fingers
- Mild to moderate pain or tenderness, especially with movement
- A sense of pressure or discomfort if the cyst presses on a nerve
- Changes in size, with the lump sometimes appearing larger or smaller
How to Treat or Prevent It
In many cases, ganglion cysts are harmless and may go away on their own. However, if they cause pain or interfere with daily activities, consider these options:
