Nerve compression

Nerve compression in the foot and ankle happens when pressure on a nerve interferes with how it sends signals for feeling and movement. It can cause pain, tingling, burning, numbness or weakness that makes standing, walking or wearing certain shoes uncomfortable. With the right care, most people find relief and get back to their daily routines with less pain.

Anatomy of the foot and ankle

Your foot and ankle contain several nerves that branch off larger nerves in your leg and travel through narrow spaces that support movement and stability. Swelling, injury, bone changes or alignment issues can crowd these spaces and place pressure on nearby nerves.

In some cases, such as tarsal tunnel syndrome, this pressure occurs along the inside of the ankle. When that happens, symptoms may travel into the heel, arch or toes.

Overview

Symptoms

You may have nerve compression if you notice:

Tingling, burning or electric-shock sensations in the foot, heel, ankle or toes
Numbness or pins-and-needles in part of the foot
Pain that worsens with standing, walking or certain shoes
Tenderness along a nerve pathway, such as behind the inner ankle
Weakness, cramping or a feeling that the foot is unsteady
Shooting pain that travels up the leg or into the toes

Symptoms may come and go at first and become more noticeable over time if the nerve remains irritated.

Causes

Nerve compression can develop for several reasons, including:

Ankle sprains, broken bones or swelling that put pressure on nearby nerves
Flat feet or high arches that change pressure patterns in the foot
Cysts, bone spurs, varicose veins or thickened ligaments near a nerve
Arthritis, diabetes or inflammatory conditions that increase tissue swelling
Repetitive stress from running, prolonged standing or tight footwear
Prior injuries or surgery that cause irritation or scarring around a nerve

Risk factors

Certain factors can make nerve compression more likely, though having one or more of these does not mean you'll develop the condition. Risk factors include:

A history of ankle sprains, fractures or foot surgery
Flat feet, high arches or other alignment issues
Diabetes or other conditions that affect circulation and swelling
Arthritis or inflammatory conditions
Jobs or activities that involve repetitive stress, prolonged standing or tight footwear

Your foot and ankle specialist can help you understand which factors may be contributing to your symptoms.

Diagnosis

Your foot and ankle specialist will review your history, including past injuries, medical conditions and when your symptoms occur. Your visit may include a physical exam to check sensation, strength and tender areas, along with gentle tests that tap or stretch the nerve to help reproduce your symptoms. A gait analysis may be used to see how you walk, and x-rays can check for bone alignment issues or growths. In some cases, advanced testing such as nerve studies, ultrasound or MRI helps confirm which nerve is affected and where the compression is occurring.
