The Tingling Heel: Understanding Medial Calcaneal Nerve Entrapment

Have you ever experienced a sharp, burning pain or tingling sensation in your heel, especially after a long day on your feet? This could be a sign of medial calcaneal nerve entrapment, a condition that affects the nerve that runs along the inside of your ankle and into your heel.

What is the Medial Calcaneal Nerve?

The medial calcaneal nerve is a branch of the tibial nerve, responsible for providing sensation to the skin on the inner side of your heel. It's a relatively small nerve, but its entrapment can lead to significant pain and discomfort.

What Causes Medial Calcaneal Nerve Entrapment?

Several factors can contribute to this condition, including:

• Tight shoes: Shoes that are too tight or have a narrow heel can compress the nerve, especially if they are worn for extended periods. (Source: Journal of the American Academy of Orthopaedic Surgeons)
• High-impact activities: Activities like running, jumping, or prolonged standing can put extra pressure on the nerve, leading to irritation.
• Ankle sprains: Injuries to the ankle can cause swelling and inflammation, which may compress the nerve.
• Bone spurs: These bony growths can develop on the heel bone and press on the nerve.
• Tarsal tunnel syndrome: This condition involves compression of the tibial nerve at the ankle, which can also affect the medial calcaneal nerve.

Symptoms of Medial Calcaneal Nerve Entrapment

The most common symptom is heel pain, often described as sharp, burning, or tingling. The pain may worsen with prolonged standing, walking, or after exercise. Other possible symptoms include:

• Numbness or tingling in the heel
• Pain that radiates to the arch of the foot
• Sensitivity to touch on the inner side of the heel

Diagnosis and Treatment

If you suspect medial calcaneal nerve entrapment, it's important to see a doctor for a proper diagnosis. They will likely perform a physical exam, ask about your symptoms, and may order imaging tests, such as an X-ray or MRI, to rule out other conditions.

Treatment for medial calcaneal nerve entrapment typically involves conservative measures, such as:

• Rest: Avoid activities that aggravate your symptoms.
• Ice: Apply ice packs to the affected area for 15-20 minutes at a time, several times a day.
• Over-the-counter pain relievers: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation.
• Shoe modifications: Consider wearing wider, more supportive shoes with a cushioned heel. (Source: Foot & Ankle International)
• Physical therapy: A physical therapist can teach you exercises to stretch and strengthen the muscles around your ankle and foot, which can help alleviate pressure on the nerve.
• Injections: In some cases, your doctor may inject corticosteroids into the area around the nerve to reduce inflammation.

When to See a Doctor:

It's important to seek medical attention if:

• Your pain is severe or persistent
• You experience numbness or weakness in your foot
• Your symptoms are accompanied by fever or swelling

Preventing Medial Calcaneal Nerve Entrapment:

You can take steps to prevent medial calcaneal nerve entrapment, including:

• Wear comfortable, supportive shoes with a good arch support.
• Avoid prolonged standing or activities that put extra pressure on your feet.
• Stretch your calf muscles and ankles regularly.
• Maintain a healthy weight to reduce stress on your feet.

Living With Medial Calcaneal Nerve Entrapment:

While medial calcaneal nerve entrapment can be a painful condition, most people can find relief with conservative treatment. By following your doctor's recommendations and making lifestyle modifications, you can manage your symptoms and improve your quality of life. Remember, early diagnosis and treatment are crucial for a successful outcome.
