Tarsal Tunnel Syndrome

Tarsal tunnel syndrome is a nerve irritation on the inside of your ankle that can cause burning, tingling, or sharp pain into the sole of your foot. Many people notice it more after long periods of standing, walking, or running.
This condition involves the tibial nerve (and sometimes its branches) as it passes through a narrow space called the tarsal tunnel. The tunnel sits behind the bony bump on the inner ankle (medial malleolus) and under a firm band of tissue (flexor retinaculum).
Because several tendons and blood vessels share this tight space, swelling or pressure can irritate the nerve. Foot posture, tendon overload, or a past ankle injury can all contribute. For broader context on other causes of foot pain, see foot pain.
Common causes
Tarsal tunnel syndrome may develop after:
- ankle sprains or fractures (swelling and scar tissue)
- repetitive loading (long walks, running, jumping sports)
- flat feet or a collapsing arch (which can increase tunnel tension)
- tendon irritation near the tunnel (for example, tibialis posterior tendinopathy)
- systemic health factors (for example, diabetes or inflammatory arthritis)
Who commonly develops tarsal tunnel syndrome?
Tarsal tunnel syndrome often affects adults aged 30–60. It is more common in people with flat feet or a collapsing arch, those who spend long hours standing or walking, and anyone with a history of ankle injury or surgery. Runners and active adults may notice symptoms during or after training, while people with diabetes or inflammatory arthritis may experience nerve sensitivity with lower activity levels.
Symptoms
Pain is the most common symptom. It often feels like burning or “electric” discomfort along the inner ankle and into the sole of the foot. Other symptoms may include:
- tingling or pins and needles in the arch, heel, or toes
- worse symptoms after standing or walking for long periods
- night discomfort or throbbing after activity
- reduced toe strength or cramping in the foot muscles
People also ask: is it the same as a pinched nerve?
Tarsal tunnel syndrome is a type of nerve compression in the foot and ankle region. However, “pinched nerve” can also describe nerve irritation in the back, hip, or leg that refers symptoms into the foot. If your symptoms travel above the ankle or include back or leg pain, read pinched nerve and discuss your pattern with a physiotherapist.
Diagnosis
A physiotherapist or doctor can assess your symptoms, foot posture, and ankle movement. They may also test nerve sensitivity around the tunnel and check for other causes of inner-ankle or sole pain.
Sometimes, imaging or nerve tests help when symptoms persist or the diagnosis remains unclear. For a plain-language overview of diagnosis and management, see the NCBI resource on tarsal tunnel syndrome.
Physiotherapy treatment options
Treatment aims to reduce nerve irritation, calm pain, and restore confident walking and sport. Your physiotherapist may recommend a mix of the following:
- load management (adjusting walking, running, or standing time while symptoms settle)
- footwear advice and, if needed, short-term support strategies
- soft tissue treatment to reduce sensitivity in the calf and foot
- graded strengthening for the foot and lower leg
- nerve-friendly mobility drills (often called nerve glides)
- foot posture retraining, such as Active Foot Posture Correction Exercises
Other management options
Some people also use:
- orthoses or arch supports (often short-term, matched to your foot posture)
- anti-inflammatory strategies advised by your GP or pharmacist when appropriate
- guided return-to-run planning if running triggers symptoms
In more persistent cases, a doctor may discuss injection options or a surgical opinion. Surgery is usually considered when symptoms remain stubborn despite a structured period of conservative care, or when a clear structural cause needs release.
Prevention
Prevention often focuses on consistent loading and foot control:
- build training volume gradually (avoid sudden spikes)
- use supportive footwear matched to your activity
- maintain calf, ankle, and foot strength
- address recurring ankle swelling or instability early
What to do next
If you have inner ankle burning, tingling in the sole, or night pain that keeps returning, book a physiotherapy assessment. A clear diagnosis matters because several conditions can mimic each other, including plantar fasciitis, metatarsalgia, and Morton’s neuroma. Your physio can then map a plan that suits your symptoms, sport, and work demands.
