Burning Foot Pain That Won't Quit? It Could Be Tarsal Tunnel Syndrome

By Dr. Christopher Correa, DPM · Select Foot & Ankle Specialists, Cypress, TX

If you've been experiencing burning, tingling, or shooting pain along the bottom of your foot or inner ankle — especially after prolonged standing or walking — tarsal tunnel syndrome could be the culprit. It's one of the most misdiagnosed and under-treated causes of chronic foot pain, and it's something we see regularly here at Select Foot and Ankle Specialists in Cypress, TX.

The good news is that once properly diagnosed, tarsal tunnel syndrome is very treatable — often without surgery. Here's everything you need to know.

What Is Tarsal Tunnel Syndrome?

Tarsal tunnel syndrome (TTS) occurs when the posterior tibial nerve — which runs along the inner ankle — becomes compressed inside a narrow passage called the tarsal tunnel. This tunnel is formed by the bones of the ankle and a thick band of tissue called the flexor retinaculum that holds the tendons, nerves, and blood vessels in place as they travel from the leg into the foot.

When the tibial nerve gets compressed or irritated within this tunnel, it causes a characteristic pattern of nerve-related symptoms — burning, tingling, numbness, or shooting pain — that radiates along the inner ankle and bottom of the foot, and sometimes up into the calf or down into the toes.

Think of it as the foot's version of carpal tunnel syndrome in the wrist — same mechanism, different location.

⚠️ Important: Tarsal tunnel syndrome is often confused with plantar fasciitis, peripheral neuropathy, or general heel pain. The distinction matters because the treatment is completely different. Getting an accurate diagnosis from a foot and ankle specialist is essential before starting any treatment.

Symptoms of Tarsal Tunnel Syndrome

Symptoms vary in severity depending on how much the nerve is being compressed, but the most common complaints we hear from Cypress patients include:

• Burning, tingling, or "electric" pain along the inner ankle and sole of the foot

• Numbness in the heel, arch, or toes — sometimes described as a "pins and needles" sensation

• Shooting or radiating pain that travels up the calf or down into the toes

• Pain that worsens with prolonged standing, walking, or activity

• Symptoms that improve with rest but return quickly once back on your feet

• A feeling of swelling or tightness inside the ankle even when no visible swelling is present

• Pain or sensitivity when pressing on the inner ankle (a positive Tinel's sign)

In more severe cases, patients may notice weakness in the small muscles of the foot or difficulty feeling temperature differences between the affected and unaffected foot.

What Causes Tarsal Tunnel Syndrome?

Tarsal tunnel syndrome can develop from a variety of causes — anything that increases pressure within the tarsal tunnel or irritates the tibial nerve can trigger it. Common causes include:

Structural factors

• Flat feet (fallen arches) — the most common structural cause, as pronation stretches and compresses the nerve

• Bone spurs within the tarsal tunnel

• Ganglion cysts, lipomas, or other soft tissue masses pressing on the nerve

• Varicose veins or abnormal blood vessels within the tunnel

Injury-related causes

• Ankle sprains — especially when the ligaments around the tarsal tunnel are overstretched

• Fractures of the ankle or heel bone that narrow the tunnel

• Post-traumatic scarring or inflammation within the tunnel

Systemic conditions

• Diabetes — increases susceptibility to nerve compression injuries

• Arthritis — inflammatory joint disease can cause swelling that compresses the nerve

• Hypothyroidism — can cause fluid retention that increases pressure in tight spaces like the tarsal tunnel

How Is Tarsal Tunnel Syndrome Diagnosed?

Accurate diagnosis requires a thorough evaluation — this is not a condition that can be self-diagnosed or guessed at based on symptoms alone, as several other conditions look nearly identical.

At Select Foot and Ankle Specialists in Cypress, Dr. Correa's diagnostic process typically includes:

Physical examination

A careful hands-on exam checking for tenderness along the tibial nerve, a positive Tinel's sign (tapping on the nerve produces a tingling or shock sensation), and assessment of foot structure and alignment. The pattern and distribution of symptoms tells us a great deal about where exactly the nerve is being compressed.

Imaging

X-rays are taken to evaluate bone structure and look for bone spurs, fractures, or joint changes that could be contributing to compression. Advanced imaging such as MRI may be ordered to look for soft tissue masses, ganglion cysts, or other structures pressing on the nerve that wouldn't show on X-ray.

Nerve conduction studies (NCS) / Electromyography (EMG)

In some cases, nerve conduction testing is helpful to confirm tibial nerve compression, measure the degree of nerve dysfunction, and rule out peripheral neuropathy or other systemic nerve conditions. This is especially important when the diagnosis is uncertain or when surgical planning is being considered.

💡 One of the most clinically reliable signs of tarsal tunnel syndrome is a positive Tinel's sign at the inner ankle. Dr. Correa will tap gently along the tarsal tunnel — if this reproduces your symptoms (tingling, shooting pain, numbness into the foot), that strongly suggests tibial nerve compression.

Conservative Treatment for Tarsal Tunnel Syndrome

The majority of tarsal tunnel syndrome cases respond well to conservative treatment, particularly when caught before significant nerve damage has occurred. At our Cypress clinic, we always exhaust non-surgical options before considering any procedure.

Custom orthotics

For patients with flat feet or abnormal foot mechanics, custom orthotics are often the most effective conservative intervention. By correcting pronation and supporting the arch, we reduce the stretching and compression forces on the tibial nerve. Many patients notice significant improvement within 4–8 weeks of consistent orthotic use.

Activity modification and rest

Reducing or temporarily stopping activities that aggravate symptoms allows nerve inflammation to settle. This doesn't mean complete immobilization — low-impact activities like swimming or cycling can often continue — but high-impact repetitive loading like running or prolonged standing should be reduced.

Anti-inflammatory medications

Oral NSAIDs (ibuprofen, naproxen) help reduce nerve inflammation and are often used in the acute phase. For more significant or persistent inflammation, targeted corticosteroid injections directly into the tarsal tunnel can provide substantial relief and are highly effective in many cases.

Physical therapy

A targeted PT program focuses on reducing nerve tension, strengthening the muscles that support the arch, improving ankle stability, and addressing any biomechanical issues contributing to nerve compression. Nerve mobilization techniques performed by an experienced therapist can also be very helpful.

Bracing and immobilization

In acute or severe cases, a short period of immobilization in a walking boot can allow significant nerve irritation to calm down before beginning rehabilitation. Night splints are also sometimes used to maintain a neutral foot position overnight.

Laser therapy

At Select Foot and Ankle Specialists, we offer the Remy Class IV laser as an adjunct treatment for nerve pain. Laser therapy has shown promising results in reducing inflammation and promoting nerve healing in compression syndromes like tarsal tunnel. It's non-invasive, painless, and can be combined with other conservative treatments for enhanced results.

Surgical Treatment: Tarsal Tunnel Release

When conservative treatment has been given a thorough trial — typically 3 to 6 months — and symptoms persist or worsen, surgery becomes an appropriate consideration. Tarsal tunnel release is the standard surgical procedure and has an excellent track record when performed on properly selected patients.

What the procedure involves

Tarsal tunnel release is performed under local or regional anesthesia, often as an outpatient procedure. The surgeon makes an incision along the inner ankle and carefully divides the flexor retinaculum — the tight band of tissue forming the roof of the tarsal tunnel — to decompress the tibial nerve and its branches.

If a specific cause of compression is identified — such as a bone spur, ganglion cyst, or abnormal blood vessel — this is addressed at the same time. The nerve is carefully inspected throughout its course and any areas of scarring or internal fibrosis within the nerve may also be released (internal neurolysis) in appropriate cases.

What to expect after surgery

Recovery from tarsal tunnel release is gradual. Most patients are placed non-weight bearing in a protective boot or splint for the first 2–3 weeks to allow the incision to heal. Weight bearing is typically resumed within the first week in a protected fashion. Return to normal footwear usually occurs around 4–6 weeks post-operatively, with full activity resumption at 2–3 months.

Nerve recovery is slower than soft tissue healing — it's not uncommon to continue noticing gradual improvement in symptoms for 6–12 months following surgery as the tibial nerve fully heals and regenerates.

Expected outcomes

Outcomes from tarsal tunnel release are good to excellent in most patients when the diagnosis is accurate and surgery is performed at the right time. Studies report symptom improvement in 75–90% of properly selected surgical candidates. The best outcomes are seen in patients who had a clear identifiable cause of compression (such as a cyst or bone spur) and those who did not have significant pre-existing nerve damage prior to surgery.

At Select Foot and Ankle Specialists, Dr. Correa will thoroughly discuss your individual case, imaging findings, and realistic expectations before any surgical decision is made. Surgery is never rushed — it is always the final step after conservative measures have been fully explored.

💡 The single biggest predictor of surgical success in tarsal tunnel syndrome is accurate diagnosis. This is why we invest heavily in the diagnostic process before recommending any intervention. If you've been told you have plantar fasciitis but your treatments aren't working, it's worth getting a second opinion — tarsal tunnel syndrome is frequently the true diagnosis.

When Should You See a Doctor?

Don't wait if you're experiencing any of the following:

• Burning or tingling in the foot or inner ankle that has lasted more than 2–3 weeks

• Symptoms that are worsening despite rest

• Numbness that is spreading or affecting your balance

• Foot pain that is interfering with your daily activities or sleep

• You have diabetes or a history of nerve problems — nerve compression can escalate quickly

Early intervention leads to faster, more complete recovery. The longer a nerve is compressed, the more difficult it becomes to fully restore normal function. If you're in the Cypress, TX area, we can typically get new patients in within the same week.

The Bottom Line

Tarsal tunnel syndrome is a compression injury of the posterior tibial nerve at the inner ankle that causes burning, tingling, and pain along the foot's sole and heel. It's frequently misdiagnosed but responds well to treatment — both conservative and surgical — when properly identified.

The key steps are accurate diagnosis, addressing any underlying structural causes (flat feet being the most common in our Cypress patient population), and a progressive treatment approach from conservative care through surgery if needed.
