A ganglion cyst is a fluid-filled lump that typically develops along tendons or joints, most commonly in the wrists, hands, or feet. These cysts are noncancerous and can vary in size, often appearing as a smooth, round, or oval bump under the skin. Ganglion cysts are filled with a jelly-like fluid and may fluctuate in size or even disappear on their own. While they are usually painless, they can cause discomfort, pain, or limited mobility if they press on nearby nerves or joints. The exact cause of ganglion cysts is unclear, but they are often associated
with repetitive motion, joint or tendon irritation, or previous injuries.
Treatment for a ganglion cyst depends on the severity of symptoms. Non-invasive options include observation if the cyst is small and not causing discomfort or using splints or braces to reduce joint motion and relieve pain. Aspiration, where the cyst is punctured and its fluid removed, can provide temporary relief but has a risk of recurrence. For persistent or painful cysts, surgical removal may be necessary to prevent recurrence and address underlying issues. Physical therapy may also help improve joint function and reduce symptoms after treatment.
Consulting a healthcare professional is essential to determine the best approach for managing ganglion cysts.
