What is a ganglion cyst?
Ganglion cysts are fluid filled sacs that can develop over joints or tendons primarily in the hand and wrist, though can occur anywhere.
These are benign (non-cancerous). They usually don’t cause symptoms except for being able to feel a small bump, though with repetitive motion, it can lead to pain.
If the cyst is located over a nerve, it can cause tingling and even weakness to the muscles around it.
They can occur in anyone, though most commonly affect women between ages of 20 and 40 for unknown reasons.
Treatment options typically are conservative with many cases resolving on their own with a temporary splint and prevention of repetitive movements of the affected area.
Other options include draining the cyst with a needle and sometimes surgery.
If you are concerned you have a ganglion cyst, see your primary care or a hand physician for further evaluation.
