A ganglion cyst is a fluid-filled sac that appears as a lump, usually at the top or underside of a joint or a tendon. Ganglion cysts most commonly occur on the hand and wrist, but can also appear on the foot or ankle, or around other joints, such as fingers. When they occur on a finger, they are called mucous cysts.
When to Seek Treatment for a Ganglion Cyst
In some cases, a lump is the only sign of a ganglion cyst. But if the cyst puts pressure on nearby nerves, it can cause discomfort, pain, tingling, or muscle weakness. It can also interfere with your grip strength or range of motion. If you’re having symptoms like these, it’s a good idea to see an orthopaedic specialist for a thorough evaluation and to learn about your treatment options.
