Start with understanding
Tarsal tunnel syndrome involves compression of the tibial nerve or its branches around the inside of the ankle. Burning, tingling, or numbness in the sole can be part of the presentation.
Those symptoms have several possible causes. Because this is an uncommon diagnosis, a careful assessment should consider other foot, nerve, and systemic explanations rather than calling every tingling foot tarsal tunnel syndrome.

Connect understanding to daily life
Make the symptom map useful
Describe exactly where the sensation occurs: heel, arch, toes, or more of the foot. Note whether it affects one side or both and whether footwear, standing, or another activity changes it. Bring any recent injury and relevant medical history to the appointment. These details help narrow the question; no location on a diagram can establish the diagnosis by itself.
The assessment should stay broad
AAPM&R recommends examining the foot and ankle alongside neurologic and other relevant findings. Nerve symptoms can originate outside the tunnel, and symptoms in both feet can prompt a different set of questions. Ask which alternatives are being considered and whether another clinician should be involved. A thorough assessment is more useful than selecting a treatment solely because it targets the place you feel discomfort.
Tests can help without being perfect
Nerve-conduction studies may help support a suspected diagnosis, but evidence about their diagnostic accuracy is limited. Ask what question a proposed test can answer, what a normal result would mean, and what the next step would be if uncertainty remains. An examination sign or test result should be interpreted with the rest of your story rather than treated as a final verdict.
Choose changes for a reason
Depending on findings, a clinician may discuss pressure from footwear, an identifiable local cause, or a rehabilitation or specialist plan. Explain the shoes and activities your day actually requires so recommendations can be practical. Do not repeatedly stretch or press a tingling area to see whether you can fix it. Agree on what to try and how you will judge whether it helps.
Keep changing sensation in the conversation
Seek prompt assessment for increasing numbness, new weakness, or symptoms that keep limiting daily activity. A suddenly cold or discolored foot needs urgent medical attention. If you have diabetes, foot symptoms deserve timely review. The goal is to identify an appropriate explanation and plan, not to fit every foot symptom into this label or wait indefinitely for it to settle.
Educational information complements individual guidance. Your health history, goals, and examination determine appropriate care.
Build your understanding
Five ideas to build your understanding. Swipe, use the arrows, or focus the slides and use your keyboard.
Is burning under my foot definitely tarsal tunnel syndrome?
No. Several conditions can cause burning or tingling. A clinician should assess the pattern and consider other explanations.
Can a normal nerve test settle the question?
Not always. Test accuracy is imperfect, so the clinician needs to interpret the result alongside your history and examination.
What the evidence means for you
Assessment should consider competing explanations
AAPM&R describes overlapping foot and nerve conditions and recommends a broader examination.
Put it to use: Bring a precise symptom map and ask what else could explain the pattern.
Keep in mind: The professional overview cannot confirm a diagnosis from symptoms alone.
American Academy of Physical Medicine and Rehabilitation, updated 2025 →Nerve tests can support the evaluation
The AANEM evidence review found that nerve-conduction studies may help confirm tibial neuropathy at the ankle.
Put it to use: Ask what a nerve test would add and how either result would affect care.
Keep in mind: The review is older and based on few lower-quality studies; sensitivity and specificity could not be established.
