Tarsal tunnel syndrome is not as widely recognized as heel pain or ankle sprain, but it can cause very troublesome symptoms in the foot. I usually explain it as pressure on the tibial nerve or one of its branches as the nerve passes through a narrow channel on the inner side of the ankle. When that nerve becomes compressed or irritated, patients may develop burning pain, tingling, numbness, or unusual sensitivity in the sole of the foot or around the inner ankle. Because patients often confuse it with more general foot or leg strain, it can help to compare it with other overuse problems such as [shin splints](/shin-splints/) and broader guidance on [when to see an orthopedic surgeon](/when-should-you-see-an-orthopedic-surgeon-in-bangladesh/).
In Bangladesh, this problem is often ignored for too long because many people assume the discomfort is just due to standing too much, walking too much, or wearing poor footwear. Those factors may contribute, but persistent nerve-type symptoms in the foot deserve a more careful look. Early diagnosis matters because long-standing nerve compression can become harder to settle.
What Tarsal Tunnel Syndrome Actually Means
The tarsal tunnel is a narrow space near the inside of the ankle. Important tendons, blood vessels, and the tibial nerve pass through it. If swelling, inflammation, structural pressure, or abnormal foot mechanics reduce the available space, the nerve may become irritated. That is why symptoms are often more than simple pain. Patients may describe burning, tingling, numbness, electric-shock sensations, or a feeling that the sole is not normal. [1]
This is different from conditions such as plantar fasciitis, which usually causes heel pain related more to the fascia than to a nerve. The symptoms can overlap, which is one reason tarsal tunnel syndrome is sometimes missed at first.
Common Symptoms Patients Notice
The symptoms are not identical in every person, but some patterns are common. Many patients feel discomfort along the inner ankle that travels into the arch or sole. Some notice tingling in the toes. Others report burning that becomes worse after standing or walking. Night symptoms can occur in some people, especially when nerve irritation has become more established.
In my practice, I often pay close attention when a patient says the foot pain feels different from ordinary soreness. Nerve pain has its own character. It may burn, travel, or produce numbness rather than only local tenderness. Some patients also say slippers feel uncomfortable, or that prolonged standing at work makes the sole feel irritated and abnormal.
Why It Happens
Tarsal tunnel syndrome is not one single disease with one single cause. It is a nerve compression problem, and the reason behind the compression can vary. Sometimes swelling develops after an ankle injury. Sometimes flat foot posture changes the mechanics and increases strain around the tunnel. Sometimes tendon inflammation, cysts, varicose veins, scar tissue, or arthritis contribute to pressure in the area.
In Bangladesh, where many people spend long hours on their feet in shops, factories, clinics, schools, or household work, repeated strain may expose a vulnerable foot to more symptoms. That does not mean prolonged standing alone causes the condition, but it can make a pre-existing compression problem more obvious.
Conditions That Can Be Mistaken for It
This is an important part of the discussion because not every tingling foot means tarsal tunnel syndrome. Plantar fasciitis, diabetic nerve disease, lower back nerve irritation, inflammatory joint conditions, local tendon problems, and circulation-related issues can all confuse the picture. If the diagnosis is made too quickly, treatment may go in the wrong direction.
That is why I do not advise patients to self-diagnose simply from internet reading. A foot that burns or feels numb needs careful clinical assessment, especially if the patient also has diabetes, chronic back pain, prior ankle injury, or visible swelling.
