Tarsal Tunnel Release Recovery
Posterior Tibial Nerve Decompression at the Tarsal Tunnel
What the operation does
The tibial nerve passes behind the inner ankle bone through a tunnel roofed by a tight band of tissue, then divides to supply the sole. Where it is compressed there, the roof of the tunnel is divided along its length to give the nerve room, and anything pressing on it — a cyst, a swollen tendon sheath, an extra muscle, scar tissue — is dealt with at the same time.
What the symptoms come from
Burning, tingling, numbness or shooting pain in the sole and toes, often worse at night or after standing, sometimes with an electric feeling when the inner ankle is tapped. Those are nerve symptoms rather than joint or tendon ones, which is why they do not behave like ordinary foot pain and why rest often does not help them.
An honest word about how reliable this is
This deserves stating plainly, because expectations here matter more than in most foot operations. Tarsal tunnel release is less predictable than the equivalent operation at the wrist. Results are best where a specific cause was found and removed — a cyst, a swollen sheath, an extra muscle. Where scans and tests showed nothing definite compressing the nerve, the outcome is less certain, and your surgeon will have weighed that before recommending it.
Why finding a cause matters so much
A nerve with something identifiable pressing on it usually recovers once the pressure is gone. A nerve that has been irritated for a long time without a clear compression may have changed in itself, and releasing the tunnel gives it room without undoing that. It is the single strongest predictor of how much this helps.
How nerves recover, and how slowly
Nerve recovery is measured in months, not weeks. Regrowth happens at roughly a millimetre a day, so improvement after a release is gradual and continues for up to a year or more. Some people notice relief of the burning within days; the numbness usually takes far longer, and some of it may not return.
Symptoms that get louder before they get quieter
Tingling, pins and needles, or an increase in odd sensations in the weeks after surgery is common and often a sign of the nerve waking up rather than of a problem. It can be unsettling if you were not expecting it. Steadily worsening pain, as opposed to changing sensation, is different and worth reporting.
Weight and the boot
Practice varies. Many people are allowed weight early in a boot or supportive shoe, sometimes with a short period of limited weight to protect the wound, which sits in an awkward place for healing. Your surgeon will be specific.
Protecting the wound
The incision curves behind the inner ankle where the skin moves with every step, so it is under more tension than most and is watched more carefully. Keep it dry and covered as instructed. If it starts leaking, opening, or becoming red and increasingly sore, contact your care team promptly rather than waiting.
Scar tissue around the nerve
The nerve was released from scar and can become tethered in new scar as it heals, which is one reason gentle ankle and toe movement is encouraged early — it keeps the nerve gliding rather than sticking. It is also why a second operation for the same problem is generally less successful than the first.
If you have reduced feeling in the foot
Where sensation is impaired, the usual warning signals are missing and a sore spot or blister may go unnoticed until established. Checking the foot daily, including the sole and between the toes, becomes a sensible routine, along with well-fitting shoes.
Swelling
The inner ankle and foot swell for weeks to months, worse in the evening. Elevation in the early weeks helps, and swelling around a recently released nerve can itself aggravate symptoms, so it is worth taking seriously.
Driving and work
For a right foot, driving generally waits until you are out of the boot, walking comfortably, and could brake hard without hesitating — commonly around four to six weeks. Desk-based work is often possible within one to two weeks; work on your feet commonly six to ten weeks.
What good looks like
Often partial rather than complete, and worth defining in advance. Most people who improve describe the burning and night pain settling first and most convincingly, with numbness improving more slowly and sometimes incompletely. Judging the result before six months usually undersells it.
How the first year usually unfolds
Two weeks dominated by the wound and gentle movement. Two to six weeks brings walking and normal shoes, with sensations often still changeable. Six weeks to three months brings the burning and night symptoms settling for most people. Three to twelve months is where numbness improves, slowly, and where the final result becomes clear.
Staying in touch with your care team
Whether a specific cause was found changes what to expect considerably, and your surgeon knows what they saw. If something about your recovery is worrying you or does not match what is described here, contact your care team — they would far rather hear from you.
