Ganglion cysts are typically treated with wrist or finger splints, hydrocortisone injections, by aspirating the fluid from the cyst with a needle, or by surgically removing the cyst, reports WebMD. Cysts frequently disappear on their own without any treatment.
Ganglion cysts form from synovium, the tissue surrounding a joint or tendon that produces lubricating fluid for these structures, explains MedicineNet. The cysts, like small sacs, develop and fill with this viscous fluid for unknown reasons, sometimes as a result of trauma to the joint or tendon. They usually appear around the wrists and hands but can also develop on feet, knees, ankles and shoulders, reports WebMD.
Ganglion cysts are non-cancerous, vary in size from minuscule to larger than a cherry, and frequently appear very suddenly. Cysts can grow larger as activity causes fluid in the sac to accumulate but also can shrink or break down, disappearing altogether. Usually these cysts do not cause any symptoms, but they can exert pressure on nerves, causing pain or weakness. They may also affect grip or joint movement, states WebMD.
Treating ganglion cysts with a wrist or finger splint is often sufficient to cause it to break down and disappear, asserts WebMD. Further treatment can be through draining the fluid from the cyst with a needle and syringe, sometimes accompanied by hydrocortisone injections, states MedicineNet. The entire cyst can also be removed through surgery.
