Tarsal Tunnel Syndrome: Causes, Symptoms & Relief

Written by Sweeney Content Team | Apr 17, 2026 9:06:02 PM

When most people hear the term “nerve compression,” they think of carpal tunnel syndrome in the wrist. But did you know a very similar condition can occur in your foot?

Tarsal Tunnel Syndrome (TTS) is often called the “carpal tunnel of the foot,”  and while it’s less common, it can be just as disruptive to your daily life. From burning pain to tingling sensations, this condition can make walking, standing, and even resting uncomfortable.

 

At Sweeney Foot & Ankle Specialists, we help patients identify and treat nerve-related foot conditions like TTS every day. Here’s what you need to know and how to find relief.

What Is Tarsal Tunnel Syndrome?

Tarsal tunnel syndrome occurs when the posterior tibial nerve becomes compressed as it travels through a narrow space on the inside of your ankle called the tarsal tunnel.

 

This tunnel is made up of bone and a strong ligament, leaving very little room for swelling or pressure. When inflammation or structural issues occur, the nerve gets squeezed, leading to pain and abnormal sensations in the foot.

Think of it like this:

  • Carpal tunnel syndrome = nerve compression in the wrist
  • Tarsal tunnel syndrome = nerve compression in the ankle/foot

How Common Is It?

Tarsal tunnel syndrome is considered relatively rare, but that doesn’t mean it’s insignificant.


  • It’s often underdiagnosed, meaning more people may have it than are reported
  • Women are up to 3 times more likely to develop the condition
  • Peak onset typically occurs between the ages of 40 and 60

Interestingly, certain groups have a higher risk:

  • People with flat feet (fallen arches)
  • Individuals who stand for long periods (common in service or healthcare jobs)
  • Athletes or runners
  • Patients with inflammatory conditions like arthritis

What Causes Tarsal Tunnel Syndrome?

TTS isn’t always caused by one single issue. It’s often the result of anything that increases pressure inside the tarsal tunnel.

 

Common causes include:

  • Overuse or Repetitive Stress: Running, prolonged standing
  • Flat Feet: Which stretches the nerve
  • Ankle Injuries: Sprains or fractures
  • Swelling or Inflammation: In the ankle area 
  • Varicose Veins or Cysts: Pressing on the nerve
  • Underlying Conditions: Diabetes or arthritis

In fact, studies show that doctors can identify a specific cause in 60–80% of cases, while the rest are considered idiopathic (no clear cause).

Recognizing the Symptoms

Tarsal tunnel syndrome can be tricky because symptoms often mimic other foot conditions like plantar fasciitis.

Common symptoms include:

  • Burning pain along the inside of the ankle or the bottom of the foot
  • Tingling or “pins and needles” sensations
  • Numbness in the toes or sole
  • Electric shock-like feelings
  • Pain that worsens with activity and improves with rest

Symptoms may also radiate up the leg or across the foot, depending on which branch of the nerve is affected.

 

One hallmark sign doctors look for is a positive Tinel’s sign, a tingling sensation when tapping over the nerve.

Why It’s Often Misdiagnosed

One of the biggest challenges with TTS is that it’s frequently mistaken for other conditions.

 

Because heel pain is so common, affecting up to 10% of adults at some point, many cases are initially attributed to plantar fasciitis.

 

Additionally:

  • Symptoms can be vague or inconsistent
  • Diagnostic criteria aren’t fully standardized
  • Imaging and nerve tests aren’t always definitive

This is why seeing a foot and ankle specialist is critical for accurate diagnosis.

How Is Tarsal Tunnel Syndrome Diagnosed?

A proper diagnosis starts with a detailed evaluation, including:

  • Medical history and symptom review
  • Physical examination of the foot and ankle
  • Nerve testing 
  • Imaging, such as MRI or ultrasound, to identify structural causes (when needed)

At Sweeney Foot & Ankle Specialists, we take a comprehensive approach to ensure nothing is overlooked, especially when symptoms overlap with other conditions.

Treatment Options: Finding Relief

The good news? Many patients find relief with non-surgical treatments, especially when the condition is caught early.

 

Conservative (Non-Surgical) Treatments: 

  • Rest and activity modification
  • Anti-inflammatory medications
  • Custom orthotics to support the arch
  • Physical therapy to improve foot mechanics
  • Bracing or supportive footwear
  • Steroid injections to reduce inflammation

These approaches aim to relieve pressure on the nerve and reduce symptoms.

 

Advanced Options (Permanent Nerve Damage): 

For more persistent cases:

  • Magnetic insole therapy 
  • Galvanic Nerve Stimulation
  • You may also be referred to a pain medicine specialist

When Is Surgery Needed?

Surgery is typically considered only when conservative treatments fail.

A tarsal tunnel correction procedure involves relieving pressure on the tibial nerve by opening the tunnel. While outcomes vary, many patients experience significant improvement, especially when treatment isn’t delayed.

Why Early Treatment Matters

Like many nerve conditions, timing is everything.

The longer the nerve remains compressed:

  • The higher the risk of permanent nerve damage
  • It can be more difficult to fully resolve symptoms

Research shows that patients with longer symptom duration tend to have poorer outcomes, even after treatment.

When to See a Specialist

If you’re experiencing persistent foot pain, numbness, or tingling, it’s worth getting evaluated, especially if symptoms:

  • Don’t improve with rest
  • Worsens over time
  • Interfere with walking or daily activities

Early diagnosis can make all the difference in avoiding long-term complications.

Take the First Step Toward Relief

Tarsal tunnel syndrome may be less well-known than its wrist counterpart, but its impact on your mobility and quality of life is just as real.

 

The good news is that with the right diagnosis and treatment plan, relief is absolutely possible.
