Do you get a ganglion from an injury?

Good question.: The cause of ganglion cysts isn't really known, but they do tend to occur on the distal extremities, so the role of trauma or repeated micro-tramua probably can't be entirely ruled out.

Sometimes: Ganglion cyst is a synovial cyst arising from a joint or tendon sheath.This usually requires a tear or defect in the joint capsule or tendon sheath that can oftentimes be the result of an injury, or repetitive trauma
