Tarsal Tunnel Syndrome
Tarsal Tunnel Syndrome is a condition caused by the compression of the posterior tibial nerve as it passes through the tarsal tunnel, a narrow space on the inside of the ankle. This nerve compression can lead to pain, tingling, or numbness in the foot and ankle, often worsening with activity. At RAD Clinics, we offer tarsal tunnel syndrome treatment, including ultrasound-guided tarsal tunnel block injections, to effectively relieve symptoms and improve mobility, enabling you to resume an active, pain-free lifestyle.

Causes of Tarsal Tunnel Syndrome
Tarsal Tunnel Syndrome can be triggered by several factors, including:
- Injury or trauma: Sprains, fractures, or other injuries around the ankle can compress or irritate the nerve.
- Overuse: Prolonged standing, running, or high-impact activities can place excessive strain on the tarsal tunnel.
- Swelling or inflammation: Conditions like tendonitis or arthritis can narrow the tunnel, leading to nerve compression.
- Flat feet or fallen arches: These conditions can cause excessive stretching or strain on the posterior tibial nerve.
- Cysts or growths: Tumours, ganglion cysts, or varicose veins within the tarsal tunnel can press on the nerve.
Symptoms of Tarsal Tunnel Syndrome
Common symptoms of tarsal tunnel syndrome include:
- Pain: A burning, shooting, or aching sensation in the ankle, foot, or toes.
- Numbness: Loss of sensation in the bottom of the foot or toes.
- Tingling or “pins and needles”: Especially noticeable after prolonged activity or standing.
- Swelling or tenderness: The area around the ankle may become inflamed or sensitive to touch.
- Worsened symptoms with activity: Running, walking, or standing often exacerbate discomfort.
Anatomy of the Tarsal Tunnel
The tarsal tunnel is located along the inner side of the ankle, formed by the bones of the ankle and the flexor retinaculum (a thick band of connective tissue). The posterior tibial nerve, along with blood vessels and tendons, passes through this tunnel. When the space within the tarsal tunnel is reduced or the nerve becomes compressed, symptoms of tarsal tunnel syndrome develop.
Tarsal Tunnel Pain Relief
At RAD Clinics, we provide tarsal tunnel syndrome injections, which are part of our advanced tarsal tunnel syndrome relief options. These injections are designed to target the underlying cause of the pain and provide long-lasting relief.
Diagnosis of Tarsal Tunnel Syndrome
Diagnosing tarsal tunnel syndrome typically involves:
- Physical examination: A clinician will examine the foot and ankle, checking for tenderness, swelling, or reproduction of symptoms when pressure is applied to the tarsal tunnel.
- Nerve conduction studies: These tests evaluate the function of the posterior tibial nerve and confirm the presence of compression.
- Imaging tests: Ultrasound or MRI scans may be used to identify structural abnormalities or soft tissue issues within the tarsal tunnel.

Ultrasound-Guided Tarsal Tunnel Block
At RAD Clinics, we provide ultrasound-guided tarsal tunnel block injections as part of our comprehensive tarsal tunnel syndrome treatment. This minimally invasive procedure delivers anaesthetic and corticosteroid medication to the affected nerve, relieving pain and reducing inflammation.
Benefits of Ultrasound-Guided Tarsal Tunnel Block
- Precision: Real-time ultrasound imaging ensures accurate delivery of medication to the affected nerve.
- Minimally invasive: The procedure avoids surgery and uses a fine needle for injection.
- Symptom relief: Pain, tingling, and numbness are alleviated, restoring comfort and mobility.
- Reduced inflammation: Corticosteroids decrease swelling around the nerve, promoting healing.
- Quick recovery: Most patients experience minimal downtime and can resume activities soon after treatment.
What to Expect During the Procedure
- Preparation: The treatment area is cleaned, and a local anaesthetic may be applied to minimise discomfort.
- Injection: Using ultrasound guidance, the clinician inserts a fine needle into the tarsal tunnel to deliver the medication precisely around the nerve.
- Post-procedure care: Some mild soreness at the injection site is normal and should subside within a few days.
When to Seek Treatment
Professional intervention may be necessary if:
- Symptoms persist despite rest, footwear modifications, or over-the-counter pain relief.
- Pain interferes with walking, standing, or daily activities.
- Numbness or tingling worsens, affecting balance or foot function.
- Chronic discomfort reduces quality of life and limits mobility.
At RAD Clinics, our tailored approach to treating tarsal tunnel syndrome ensures effective relief and long-term recovery, helping you stay active and pain-free.
