Snapping in the foot or ankle is a condition in which you feel a snapping sensation or hear a popping sound in your foot when you move your lower extremities. The snapping sensation occurs when a muscle or tendon (the strong tissue that connects muscle to bone) moves over a bony protrusion in your feet.
Although snapping anywhere is usually painless and harmless, the sensation can be annoying. In some cases, snapping in the foot can lead to bursitis, a painful swelling of the fluid-filled sacs that cushion the joints.
When tendon snapping/popping follows major trauma, tearing of support soft tissue structures may have occurred and warrants an orthopedic consult if the snapping is either painful or limits function.
