Finger Cysts

Finger Cysts: Causes, Symptoms, and Treatment

Finger cysts, also called a digital mucous cyst, is a benign, fluid-filled sac that typically develops near the nail bed. These cysts are most common in adults over the age of 40 and may result from joint degeneration or trauma to the finger. People with osteoarthritis or prior joint injuries are more likely to develop them.

Finger cysts are often painless but can cause tenderness if they press on surrounding tissues. They usually appear as small, firm lumps with a smooth, translucent surface that may look slightly bluish. Some cysts may rupture, releasing a thick, gelatinous fluid.

Treatment options include observation, splinting, or surgical removal. While finger cysts are not usually harmful, they can be bothersome and may interfere with daily activities. Anyone experiencing pain or limited hand function should consult a healthcare provider for evaluation and management.
