Quick answer: Treatment for tarsal tunnel syndrome causes treatment follows a stepwise approach: 1) conservative care first (rest, ice, supportive footwear, OTC anti-inflammatories), 2) physical therapy and targeted exercises, 3) in-office treatments (injections, custom orthotics) if conservative fails at 4-6 weeks, 4) surgery for refractory cases. Most patients resolve at step 1 or 2. Call (810) 206-1402.

Tarsal tunnel syndrome is one of the most underdiagnosed causes of chronic foot and ankle pain. Because its symptoms overlap with plantar fasciitis and peripheral neuropathy, it’s frequently misidentified and mistreated. Understanding the condition is the first step toward effective management.
The most important clinical decision with Tarsal Tunnel Syndrome Causes Treatment isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.

What Is the Tarsal Tunnel?
The tarsal tunnel is a narrow space on the inside (medial side) of the ankle, bounded by the ankle bones and a thick ligament called the flexor retinaculum. Through this tunnel run the tibial nerve, major blood vessels, and several tendons. When the tibial nerve is compressed in this space, tarsal tunnel syndrome develops.
Causes of Tarsal Tunnel Syndrome
Common causes include flat feet (which increase medial ankle tension), ankle sprains that cause swelling compressing the tunnel, varicose veins or cysts within the tunnel, ganglion cysts, and systemic conditions like diabetes that predispose to nerve compression. Sometimes the cause is idiopathic (no identifiable cause).
Symptoms
The hallmark symptom is burning, tingling, or electrical pain along the bottom of the foot, the heel, or into the toes — typically worse with prolonged standing or walking and better with rest. Some patients experience night pain. The medial ankle may be tender to direct pressure (positive Tinel’s sign).
Diagnosis
Diagnosis involves clinical examination (Tinel’s test, dorsiflexion-eversion test), and often electrodiagnostic testing (nerve conduction studies and electromyography) to confirm nerve dysfunction. MRI can identify space-occupying lesions within the tarsal tunnel.
Conservative Treatment
First-line treatment includes custom orthotics (especially for flat-footed patients), anti-inflammatory medications, physical therapy, and corticosteroid injections. Orthotics address the underlying flatfoot mechanics that increase tibial nerve tension.
Tarsal Tunnel Release Surgery
When conservative treatment fails after 3-6 months, surgical release of the flexor retinaculum decompresses the tibial nerve. Results are variable — better outcomes are seen when a specific cause is identified and corrected (e.g., cyst removal, ankle realignment).

Dr. Tom Biernacki’s Recommendation
Tarsal tunnel syndrome is one of those diagnoses I see made too late, after patients have been treated for plantar fasciitis for a year without improvement. If you have burning, tingling, and numbness on the bottom of your foot — not just heel pain — tarsal tunnel should be on the differential. — Dr. Tom Biernacki
