Possible Causes of a Small, Movable Lump on Shin Near Ankle

Possible causes of a small, movable lump at the bottom of the shin toward the ankle include:

* Ganglion cyst: A ganglion cyst is a fluid-filled sac that forms over a joint or tendon. Ganglion cysts are most common on the wrist, but can also occur on the foot and ankle.
