Some of the techniques used to treat a ganglion cyst include surgery, aspiration, limiting movement of the affected area and letting the cyst heal on its own. The exact cause of ganglion cysts on the hands is not known, which is why prevention may be difficult, according to WebMD.
One of the ways doctors may treat a ganglion cyst is by aspiration, which is the use of a needle to drain the fluid from the cyst. However, in some instances, the cyst may reform and will require another round of treatment by the doctor.
Another technique that is considered more effective is surgery. This technique is used in severe instances when the condition renders the person less productive with regard to day-to-day activities. Doctors may carry out this procedure when a person is experiencing excruciating pain, is unable to use the hand or is feeling numbness in the affected area, states WebMD.
In some cases, ganglion cysts grow even larger as the affected person keeps moving the hand. In such situations, doctors may immobilize the patient's hand to avoid further development of the cyst. A splint or wrist brace is usually used to immobilize the affected hand. Most cases of ganglion cysts do not cause pain and will heal on their own, according to the Mayo Clinic.
