Tarsal tunnel syndrome is often misunderstood because it shares many symptoms with other causes of heel pain. Patients commonly have questions about nerve compression, treatment options and recovery. These are some of the questions I am most frequently asked in clinical practice.
Is Tarsal Tunnel Syndrome the Same as Plantar Fasciitis?
No.
Plantar fasciosis is a degenerative condition affecting the plantar fascia, whereas tarsal tunnel syndrome is caused by compression of the posterior tibial nerve or one of its branches. Although both conditions can cause heel pain, tarsal tunnel syndrome often produces burning, tingling and numbness, which are uncommon in plantar fasciosis.
What Does Tarsal Tunnel Syndrome Feel Like?
Many patients describe burning pain, electric shock-like sensations, pins and needles or numbness affecting the heel, arch or sole of the foot. Symptoms often worsen after prolonged standing or walking and may become troublesome at night.
Can Tarsal Tunnel Syndrome Cause Numbness?
Yes.
Because the posterior tibial nerve supplies sensation to the sole of the foot, compression may produce numbness, tingling or altered sensation. In longstanding cases, these symptoms may become more persistent if the nerve remains compressed.
Can It Be Mistaken for Plantar Fasciosis?
Very commonly.
Many patients are initially treated for plantar fasciitis because heel pain is their main complaint. If burning pain, tingling or numbness are present, or if standard plantar fasciosis treatments have not helped, tarsal tunnel syndrome should be considered as a possible diagnosis.
Will an MRI Show Tarsal Tunnel Syndrome?
MRI can identify many of the structural causes of tarsal tunnel syndrome, including ganglion cysts, tendon inflammation, accessory muscles and scar tissue. However, MRI does not directly demonstrate nerve compression in every patient. It is used alongside the clinical assessment rather than replacing it.
Do I Need Nerve Conduction Studies?
Sometimes.
Nerve conduction studies may be useful in selected patients, particularly when the diagnosis is uncertain or more advanced nerve compression is suspected. However, normal nerve conduction studies do not completely exclude tarsal tunnel syndrome.
Can Orthotics Help?
They can.
If abnormal foot biomechanics, particularly excessive pronation, contribute to nerve compression, orthotics may reduce tension around the posterior tibial nerve and improve symptoms. Their effectiveness depends on the underlying cause of the condition rather than the diagnosis alone.
Will I Need Surgery?
Most patients do not.
Many people improve with conservative treatment, including footwear modification, activity management, rehabilitation and treatment of the underlying cause. Surgery is generally reserved for persistent symptoms or when a structural abnormality is clearly compressing the nerve.
How Long Does Recovery Take?
Recovery varies depending on the severity of the nerve compression and the underlying cause.
Mild cases may improve over several weeks with appropriate treatment, while longstanding nerve compression may require several months for symptoms to settle. If surgery is performed, improvement often continues for many months because nerves recover slowly.
Can Tarsal Tunnel Syndrome Come Back?
Yes, it can.
If the factors that originally caused the nerve compression are not addressed, symptoms may recur. Maintaining appropriate footwear, managing foot biomechanics and treating any underlying medical or structural conditions all help reduce the risk of recurrence.
Is Tarsal Tunnel Syndrome Permanent?
Not usually.
Many patients make an excellent recovery when the condition is recognised early and treated appropriately. However, prolonged nerve compression may result in persistent symptoms because nerves recover more slowly than many other tissues. Early diagnosis provides the best opportunity for complete recovery.
