Tarsal Tunnel Syndrome

Tarsal tunnel syndrome is a nerve compression condition that affects the tibial nerve as it passes through a narrow space on the inner side of the ankle. It can cause burning, tingling, numbness, or shooting pain in the heel, arch, or sole of the foot.

Symptoms may be mild and intermittent at first, but in some patients they become more persistent and begin to interfere with walking, standing, exercise, or sleep. Because several foot and ankle conditions can produce similar symptoms, accurate diagnosis is important before treatment is selected.

What Is Tarsal Tunnel Syndrome?

Tarsal tunnel syndrome occurs when the tibial nerve or one of its branches becomes compressed or irritated as it passes through the tarsal tunnel.

The tarsal tunnel is located behind and below the medial malleolus, the bony prominence on the inner side of the ankle. The tunnel contains the tibial nerve together with tendons and blood vessels.

When pressure inside this space increases, nerve function may be affected and neurological symptoms can develop in the foot.

What Are the Symptoms of Tarsal Tunnel Syndrome?

Common symptoms may include:

• Burning pain in the sole of the foot
• Tingling or pins-and-needles sensations
• Numbness in the heel, arch, or toes
• Shooting or electric-like pain
• Pain along the inner side of the ankle
• Symptoms that worsen with prolonged standing
• Pain during or after walking
• Night-time burning or tingling in some patients
• Reduced sensation in more advanced cases

Symptoms can vary because different branches of the tibial nerve may be affected.

Where Is Tarsal Tunnel Pain Felt?

Pain often begins around the inner ankle and may spread toward the heel, arch, sole, or toes.

Some patients describe the discomfort as burning or electrical rather than a typical mechanical ache.

The exact location depends on which portion or branch of the nerve is irritated.

What Causes Tarsal Tunnel Syndrome?

Tarsal tunnel syndrome can develop whenever pressure around the tibial nerve increases.

Possible causes may include:

• Flatfoot or altered foot alignment
• Swelling around the ankle
• Previous ankle injury
• Scar tissue
• Ganglion cysts
• Varicose veins or vascular structures
• Space-occupying masses
• Arthritis or bone changes
• Tendon swelling
• Repetitive mechanical stress

In some patients, no single obvious cause can be identified.

Tarsal Tunnel Syndrome and Flatfoot

Flatfoot can alter the position and mechanics of the ankle and may increase tension or pressure around the tibial nerve.

This is especially relevant in patients with progressive collapsing foot deformity or significant hindfoot valgus.

When flatfoot and nerve symptoms occur together, treatment should consider both nerve compression and the underlying foot alignment.

Can an Ankle Injury Cause Tarsal Tunnel Syndrome?

Yes. Swelling, scar tissue, fracture changes, or structural changes after an ankle injury can reduce the available space in the tarsal tunnel.

Symptoms may begin shortly after an injury or may appear later as swelling or scar tissue develops.

A history of trauma is therefore an important part of the diagnostic evaluation.

Tarsal Tunnel Syndrome or Plantar Fasciitis?

Tarsal tunnel syndrome and plantar fasciitis can both cause heel or arch pain, but the character of the symptoms is often different.

These conditions can occasionally coexist, so diagnosis should not be based on one symptom alone.

Tarsal Tunnel Syndrome or Peripheral Neuropathy?

Peripheral neuropathy can also cause burning, tingling, and numbness in the feet.

However, neuropathy often affects both feet in a more symmetrical distribution, while tarsal tunnel syndrome may be more localized to one side and related to the tibial nerve pathway.

Medical history, neurological examination, and additional testing may be required to distinguish these conditions.

How Is Tarsal Tunnel Syndrome Diagnosed?

Diagnosis begins with a detailed history and orthopedic examination.

The location and character of pain, areas of numbness, foot alignment, ankle motion, previous injuries, swelling, and activities that increase symptoms are assessed.

The examiner may also evaluate muscle strength and sensation in the foot to determine whether nerve function has been affected.

What Is Tinel's Sign?

During examination, gentle tapping over the tibial nerve at the inner ankle may reproduce tingling or electric sensations into the foot.

This finding is known as Tinel's sign.

A positive Tinel's sign can support the diagnosis, but it does not confirm tarsal tunnel syndrome by itself.

Are Nerve Tests Necessary?

Nerve conduction studies and electromyography may be considered when the diagnosis is uncertain or when objective assessment of nerve function is needed.

These tests can help identify abnormalities involving the tibial nerve and may also help evaluate other neurological conditions.

However, normal nerve studies do not completely exclude tarsal tunnel syndrome in every patient.

When Are MRI or Ultrasound Used?

Imaging may be useful when a structural cause of nerve compression is suspected.

Ultrasound can evaluate the nerve and nearby soft tissues dynamically, while MRI can provide detailed information about cysts, masses, tendon abnormalities, inflammation, and other structures within or around the tarsal tunnel.

Imaging is selected according to the examination findings rather than routinely required for every patient.

How Is Tarsal Tunnel Syndrome Treated?

Treatment depends on the cause and severity of nerve compression.

Mild or early symptoms may often be managed with non-surgical treatment, particularly when there is no progressive weakness or significant nerve dysfunction.

When a cyst, mass, severe structural deformity, or persistent mechanical compression is identified, more targeted treatment may be required.

Non-Surgical Treatment for Tarsal Tunnel Syndrome

Can Rest Help Tarsal Tunnel Syndrome?

Reducing activities that repeatedly aggravate symptoms can help some patients, especially when nerve irritation is related to overuse or swelling.

However, rest alone does not correct every underlying cause.

Persistent symptoms require evaluation to determine whether structural compression, foot deformity, or another neurological problem is present.

Can Orthotics Help Tarsal Tunnel Syndrome?

Orthotic support may be useful when abnormal foot alignment increases tension or pressure around the tibial nerve.

This is particularly relevant in selected patients with flexible flatfoot or excessive hindfoot valgus.

Orthotics are not appropriate for every cause of tarsal tunnel syndrome and should be selected according to the individual examination.

Are Injections Used for Tarsal Tunnel Syndrome?

Injections may be considered in selected patients when inflammation around the nerve or surrounding structures contributes to symptoms.

Because important nerves, blood vessels, and tendons pass through the region, injection treatment should be carefully planned.

It should not be used as a routine treatment without identifying the likely cause of the symptoms.

Can Tarsal Tunnel Syndrome Heal Without Surgery?

Some patients improve with treatment of the underlying cause, activity modification, footwear changes, orthotic support, and rehabilitation.

The likelihood of improvement depends on the duration of symptoms, severity of nerve compression, and whether there is a structural lesion occupying space within the tunnel.

Persistent numbness, weakness, or significant nerve dysfunction requires closer evaluation.

When Is Tarsal Tunnel Surgery Considered?

Surgery may be considered when significant symptoms continue despite appropriate non-surgical treatment and there is evidence that the tibial nerve remains mechanically compressed.

Surgical treatment may also be considered when a specific structural cause such as a cyst, mass, scar tissue, or another space-occupying problem is identified.

Patient selection is important because burning foot pain can have several causes and decompression will not treat symptoms originating from an unrelated neurological condition.

Tarsal Tunnel Release Surgery

Tarsal tunnel release is performed to reduce pressure on the tibial nerve and its branches.

The structures forming the roof of the tunnel are released, and the nerve is carefully examined along areas where compression may occur.

If a cyst, abnormal tissue, or another identifiable structure is causing compression, it may also need to be addressed during the procedure.

Does Surgery Always Stop the Numbness?

No treatment can guarantee complete recovery of nerve symptoms.

Improvement depends on the cause of compression, duration of symptoms, degree of nerve damage, associated medical conditions, and whether the diagnosis was accurate.

Long-standing nerve compression may take time to recover, and some sensory changes may persist.

Recovery After Tarsal Tunnel Surgery

Recovery depends on the extent of the procedure and whether additional foot or ankle surgery is performed at the same time.

The surgical area may initially require protection while the incision heals and swelling decreases.

Weight bearing and activity are progressed according to the individual surgical plan.

Nerve symptoms may improve gradually rather than disappearing immediately after surgery.

When Can I Walk After Tarsal Tunnel Surgery?

Walking recommendations vary according to the operation performed and wound condition.

Some patients may require temporary protection or limited weight bearing during the early postoperative period.

If tarsal tunnel release is combined with correction of flatfoot or another structural problem, recovery may be longer.

Can Tarsal Tunnel Syndrome Come Back?

Persistent or recurrent symptoms are possible.

Potential reasons include scar formation, incomplete relief of compression, progression of the underlying foot deformity, or a different neurological condition producing similar symptoms.

Recurrent symptoms should therefore be reassessed rather than automatically assumed to represent the same problem.

What Happens If Tarsal Tunnel Syndrome Is Left Untreated?

Mild symptoms may remain stable in some patients, while ongoing nerve compression can lead to increasing numbness, persistent burning pain, sensory changes, or weakness in more advanced cases.

The course varies according to the cause and severity of compression.

Progressive neurological symptoms should not be ignored.

When Should You See an Orthopedic Specialist?

An orthopedic evaluation may be appropriate if:

• You have persistent burning pain in the sole of the foot
• Numbness or tingling is increasing
• Symptoms worsen with standing or walking
• Pain begins around the inner ankle and spreads into the foot
• You notice weakness in the foot
• Symptoms began after an ankle injury
• You have flatfoot together with nerve-like symptoms
• Heel pain has not responded to treatment for plantar fasciitis
• Symptoms continue despite appropriate non-surgical treatment

Tarsal Tunnel Syndrome Treatment in Antalya

Burning or numbness in the sole of the foot can result from several different conditions, including tarsal tunnel syndrome, peripheral neuropathy, spinal nerve problems, plantar heel disorders, and other local nerve entrapments.

During an orthopedic evaluation, nerve symptoms, foot alignment, ankle movement, areas of compression, previous injuries, tendon function, and neurological findings can be assessed together.

Depending on the findings, treatment may include activity modification, footwear changes, orthotic support, rehabilitation, treatment of an underlying structural problem, or tarsal tunnel release in appropriately selected patients with persistent nerve compression.

Frequently Asked Questions About Tarsal Tunnel Syndrome

What is tarsal tunnel syndrome?

Tarsal tunnel syndrome is compression or irritation of the tibial nerve or its branches as they pass through the tarsal tunnel on the inner side of the ankle.

What does tarsal tunnel syndrome feel like?

Symptoms often include burning, tingling, numbness, shooting pain, or electric sensations in the heel, arch, sole, or toes.

Can flat feet cause tarsal tunnel syndrome?

Flatfoot may contribute in some patients by changing foot alignment and increasing tension or pressure around the tibial nerve.

Is tarsal tunnel syndrome the same as plantar fasciitis?

No. Plantar fasciitis is primarily a mechanical soft-tissue problem, while tarsal tunnel syndrome is a nerve compression condition. Their symptoms can sometimes overlap.

Can tarsal tunnel syndrome cause numb toes?

Yes. Depending on which nerve branches are affected, numbness or tingling may extend into parts of the sole and toes.

Can tarsal tunnel syndrome improve without surgery?

Yes. Some patients improve with treatment of the underlying cause, activity modification, footwear changes, orthotics, and rehabilitation.

When is surgery needed?

Surgery may be considered when significant nerve symptoms persist despite appropriate conservative treatment and mechanical compression has been identified.

Does nerve decompression work immediately?

Not necessarily. Nerve recovery can be gradual, particularly when compression has been present for a long time.

Can tarsal tunnel syndrome return?

Recurrence or persistent symptoms can occur, especially when scar tissue, structural deformity, or another neurological condition remains.

When should burning foot pain be examined?

Evaluation is appropriate when symptoms are persistent, worsening, associated with numbness or weakness, or interfere with normal walking and daily activity.
