Overview
The tibial nerve is in the back of your leg. It has many branches that enable the lower leg to receive messages from the brain.
Function
Branches of the tibial nerve connect to (innervate) muscles in the back of the leg. Tibial nerve innervation enables you to move your leg, foot and toes.
Anatomy
The tibial nerve branches off from the sciatic nerve. This nerve starts in the lower spine and innervates the lower body.
Conditions and Disorders
Tibial nerve dysfunction is a group of conditions that often cause tibial nerve pain.
Care
Eating a healthy diet with foods containing vitamin D and vitamin B12, which support nerve health.
