Tarsal tunnel syndrome symptoms usually involve tingling, burning, numbness, or a pins-and-needles feeling in the sole of the foot, often around the heel, arch, and toes. The sensation may come and go at first, appearing after standing or walking for a while and easing with rest, but it can become more constant over time. Some people describe it as an electric-shock feeling or a dull ache deep inside the foot, and it may be worse at night or after a long day on your feet. Because the symptoms resemble other foot problems, tarsal tunnel syndrome is often mistaken for plantar fasciitis or nerve pain from diabetes at first.
See a doctor promptly if you notice any of these:
- Numbness or weakness that is getting worse, or spreading up the leg
- Foot pain with a visible lump, swelling, or injury around the inner ankle
- Symptoms in both feet, or symptoms alongside diabetes or poor circulation
- Loss of muscle strength in the foot, tripping, or difficulty moving the toes
- Tingling or burning that does not improve after a few weeks of rest and better footwear
What tarsal tunnel syndrome is and why it happens
On the inside of your ankle runs a narrow passage called the tarsal tunnel, formed by bone on one side and a tough ligament on the other. Through it passes the posterior tibial nerve, which carries sensation from the sole of the foot and controls some of the small muscles there. When something compresses or irritates that nerve inside the tunnel, the result is tarsal tunnel syndrome — the foot’s version of carpal tunnel syndrome in the wrist.
Compression can come from several sources. A flat foot that rolls inward stretches and squeezes the nerve. An ankle sprain can leave scar tissue or swelling in the area. Cysts, bone spurs, varicose veins, and tumours can crowd the tunnel, and conditions like diabetes, arthritis, and thyroid problems can make nerves more vulnerable to compression. Tight shoes and repetitive standing or walking can aggravate it too.
The symptoms follow the nerve’s territory: the sole of the foot, especially the heel, arch, and the first three toes. Tingling and burning are the most characteristic signs, and they often worsen with activity and ease when you sit down and rest. Some people find the sensation shoots into the foot when the inner ankle is tapped, and night-time symptoms are common, since fluid shifts and resting positions can increase pressure on the nerve.
Because tarsal tunnel syndrome is less common than plantar fasciitis, it is frequently misdiagnosed. Plantar fasciitis typically causes sharp heel pain with the first steps in the morning, while tarsal tunnel syndrome causes tingling and burning that worsens through the day. The distinction matters, because the treatments differ.
What helps tarsal tunnel syndrome
The first step is to reduce pressure on the nerve. Rest from aggravating activity, supportive shoes with good arch support, and avoiding tight footwear around the ankle all help. Icing the inner ankle can reduce swelling, and over-the-counter pain relief may ease the ache in the short term.
Orthotics are often recommended, particularly when a flat foot is contributing to the compression, because holding the arch up reduces the stretch on the nerve. The Cleveland Clinic notes that conservative treatment — rest, ice, orthotics, and physical therapy — helps many people, and that corticosteroid injections are sometimes used to reduce swelling around the nerve. Physical therapy can also address tight calves and poor foot mechanics that add to the problem.
If symptoms persist despite several months of conservative care, or if there is a clear structural cause such as a cyst or bone spur, a clinician may discuss surgery to release the ligament and free the nerve. That decision usually follows nerve conduction studies or imaging to confirm the diagnosis.
It is also worth checking for underlying conditions. If you have diabetes, good blood sugar control helps protect nerves generally, and if symptoms affect both feet, a broader nerve problem may be at play and deserves a medical work-up rather than foot care alone.
A daily routine for tarsal tunnel symptoms
In the morning, wear supportive shoes with arch support from the start of the day, and avoid tight socks or shoes that press on the inner ankle. Gentle ankle circles can help the foot wake up without irritating the nerve.
During the day, take sitting breaks if you stand for long periods, and avoid activities that clearly worsen the tingling. If symptoms flare, rest with the foot elevated for a few minutes.
In the evening, ice the inner ankle if it feels swollen, note whether the tingling is getting better or worse over weeks, and keep a simple log of triggers. A worsening pattern is a good reason to get checked.
Frequently asked questions
What does tarsal tunnel syndrome feel like?
Most people feel tingling, burning, numbness, or pins and needles in the sole of the foot, often worse after standing or walking and better with rest. Some describe an electric-shock sensation.
Is tarsal tunnel syndrome the same as plantar fasciitis?
No. Plantar fasciitis usually causes sharp heel pain with the first steps in the morning, while tarsal tunnel syndrome causes tingling and burning that worsens through the day.
Can flat feet cause tarsal tunnel syndrome?
Yes. A foot that rolls inward stretches and compresses the nerve inside the tarsal tunnel, which is why arch supports often help.
Will tarsal tunnel syndrome go away on its own?
Mild cases sometimes settle with rest, better footwear, and orthotics. If symptoms persist for months or worsen, medical assessment is needed, since ongoing compression can damage the nerve.
When is surgery needed for tarsal tunnel syndrome?
Surgery is usually considered only when conservative treatment has failed over several months or when a structural cause like a cyst is compressing the nerve.
