Tarsal Tunnel Syndrome: Anatomy, Electrodiagnosis, and Surgi relates to foot pain — typically caused by overuse, footwear, or biomechanics. Most patients improve in 6-12 weeks with conservative care. Same-week appointments in Howell + Bloomfield Twp: (810) 206-1402.
Medically reviewed by Dr. Tom Biernacki, DPM — Board-certified foot & ankle surgeon, 3,000+ surgeries performed. Updated April 2026 with current clinical evidence. This article reflects real practice experience from Balance Foot & Ankle Specialists in Howell and Bloomfield Hills, Michigan.
Quick Answer
Most foot and ankle problems respond to conservative care — proper footwear, supportive inserts, activity modification, and targeted stretching — within 4-8 weeks. Persistent pain beyond that window, or any symptom that prevents walking, warrants a podiatric evaluation to rule out fracture, tendon tear, or systemic cause.

Tarsal tunnel syndrome (TTS) — compression neuropathy of the posterior tibial nerve (or its branches) as it passes posterior and inferior to the medial malleolus beneath the flexor retinaculum — produces medial ankle and plantar foot burning, tingling, and numbness that can be confused with plantar fasciitis, peripheral neuropathy, and radiculopathy. The distinction matters because each requires a fundamentally different treatment approach, and TTS producing a compressive lesion is surgically correctable.
Anatomy and Etiology
The tarsal tunnel — bounded by the medial malleolus anteriorly, the posterior calcaneus and talus posteriorly, and the flexor retinaculum superficially — contains the tibialis posterior tendon, flexor digitorum longus, posterior tibial artery, posterior tibial nerve, and flexor hallucis longus (Tom, Dick, And nervous Harry — the mnemonic for tunnel contents in order). The posterior tibial nerve divides within or just distal to the tunnel into the medial plantar nerve, lateral plantar nerve, and medial calcaneal branches. TTS etiology: space-occupying lesion within the tunnel (ganglion cyst — the most common surgically identifiable cause; lipoma; varicosity; exostosis), post-traumatic fibrosis after ankle fracture, and idiopathic. Pes planus (flatfoot) compresses the tarsal tunnel by traction and deformation of the tunnel contents.
Electrodiagnosis and Surgery
Nerve conduction studies: distal motor latency of the medial or lateral plantar nerve >4.5ms suggests TTS; sensory NCS of the medial plantar nerve is the most sensitive electrodiagnostic test. MRI of the tarsal tunnel is mandatory before surgery to identify space-occupying lesions that, if present, produce the highest surgical success rates (90%+). Surgical decompression: complete release of the flexor retinaculum from the medial malleolus to the abductor hallucis fascia; excision of any space-occupying lesion; neurolysis of the medial and lateral plantar nerve branches. Outcomes are significantly better with identifiable compressive etiology than idiopathic TTS. Dr. Biernacki at Balance Foot & Ankle evaluates medial ankle and plantar foot neuropathic symptoms with clinical examination and coordinates NCS/EMG for electrodiagnostic confirmation.

Many foot conditions can be managed conservatively at home, but some require professional evaluation. See a podiatrist promptly if you experience:
Pain that persists for more than 2 weeks despite rest
Swelling, redness, or warmth that isn’t improving
Numbness, tingling, or burning in the feet
A wound or sore that is not healing within 2 weeks
Any foot concern if you have diabetes or poor circulation
Nail changes that suggest fungal infection or other problems

Tarsal Tunnel Syndrome: Complete Guide to Diagnosis & Treatment
Burning, tingling, and numbness in the foot from tarsal tunnel syndrome requires expert evaluation. Our podiatrists use clinical testing, nerve conduction studies, and MRI to accurately diagnose tibial nerve compression and provide targeted treatment.
class=”mfd-patient-scenario” id=”in-our-clinic”>In Our Clinic: What We See
Clinical perspective from Dr. Tom Biernacki, DPM — Balance Foot & Ankle, Howell & Bloomfield Hills, MI:
In our Balance Foot & Ankle clinic, tarsal tunnel patients typically describe burning, tingling, or shock-like pain on the bottom of the foot, often worst at night. Unlike plantar fasciitis (sharp morning pain at the heel), tarsal tunnel causes neuropathic symptoms extending into the arch and toes. The classic exam finding is a positive Tinel’s sign over the posterior tibial nerve at the medial ankle. We assess for space-occupying lesions (ganglion, varicosity, accessory muscle) with ultrasound or MRI. Conservative management with orthotics, anti-inflammatories, and night splints resolves most cases; refractory cases may need surgical release.
class=”mfd-differential” id=”differential-diagnosis”>Differential Diagnosis: What Else Could It Be?
Not every case of tarsal tunnel syndrome is straightforward. In our clinic we routinely rule out three look-alike conditions before confirming the diagnosis. If your symptoms don’t match the classic presentation, one of these may explain the pain — which is why physical exam matters more than self-diagnosis.
Condition
How It Differs
Plantar fasciitis
Sharp morning heel pain at the medial calcaneal tubercle, NOT numbness or shooting pain into the toes.
Diabetic peripheral neuropathy
Bilateral stocking-glove distribution, progressive, affects toes first — NOT reproduced by Tinel’s at medial ankle.

If home care isn’t resolving your your foot or ankle concern, a visit with a board-certified podiatrist is the fastest path to accurate diagnosis and a personalized plan. At Balance Foot & Ankle Specialists, Dr. Tom Biernacki, Dr. Carl Jay, and Dr. Daria Gutkin offer same-day and next-day appointments at both our Howell and Bloomfield Hills offices. We perform on-site diagnostic ultrasound, digital X-ray, conservative care, advanced regenerative treatments, and minimally invasive surgery when indicated.
The most common mistake we see is: Waiting too long before seeking care. Fix: any foot pain lasting more than 4 weeks, or any sudden severe symptom, deserves a professional evaluation rather than more rest.

When to See a Podiatrist
Foot and ankle surgery in 2026 is dramatically different than a decade ago — most procedures are now minimally-invasive, outpatient, and allow weight-bearing within days. Balance Foot & Ankle surgeons have performed 3,000+ foot/ankle surgeries with modern techniques. If another surgeon has recommended a traditional open procedure, a second opinion may reveal a faster, less-invasive option.
