What is a ganglion cyst? — A ganglion cyst is a small sac of fluid that forms over a joint or tendon.
Common places for a ganglion cyst are:
●Top of the wrist (picture 1)
●Finger joints
●Top of the foot
Ganglion cysts can also form on the knee, shoulder, back, or other parts of the body.
What are the symptoms of a ganglion cyst? — The symptoms include:
●Swelling
●Pain
●Trouble moving a joint
Is there a test for ganglion cyst? — Yes. If you have a bump that looks like a ganglion cyst, the doctor or nurse will probably be able to tell what it is just by doing an exam. They might also shine a powerful light into it. If light passes through, that means the bump is filled with fluid. This tells the doctor it could be a ganglion cyst.
If the doctor or nurse is not sure what is causing your symptoms, they might order an imaging test such as an MRI or an ultrasound. Imaging tests create pictures of the inside of the body.
How is a ganglion cyst treated? — Some ganglion cysts go away without any treatment. Your doctor or nurse might wait to see if the cyst goes away on its own.
If you do get treatment, the doctor or nurse might:
●Drain the cyst – Doctors can stick a needle into a cyst and take out the fluid.
●Do surgery – The doctor might take out the cyst and fix any damaged tissue nearby.
What if my symptoms do not get better? — If your symptoms do not get better, talk with your doctor or nurse. If you have been waiting to see if the ganglion cyst goes away without treatment, you might need treatment.
