Aspiration (removal of fluid through a needle) of the ganglion cyst and injection of steroid is less invasive than ganglion resection but there is a relatively high rate of recurrence. It is reasonable to simply observe the ganglion cyst if it is causing no problems or to have it aspirated and injected to see whether this is effective before considering surgery.
Depending on several factors, including the size and location of the wound, your doctor will advise you when it is safe to return to exercise. It is usually between 2 and 6 weeks after surgery.
This is possible but unlikely. Ganglion resection will result in a scar and there is a 1 in 5 chance of the ganglion coming back after the operation.
If you have foot pain that is not related to the ganglion then this may not be relieved by ganglion resection.
