The most likely reason your heel is tingling after walking is tarsal tunnel syndrome.
Tarsal Tunnel Syndrome Explained
Tarsal tunnel syndrome is a condition where the posterior tibial nerve, which runs along the inside of your ankle and into your foot, gets compressed. This compression can lead to numbness, tingling, burning, or pain in the heel, arch, toes, and even calf. Many people describe it as a "pins and needles" sensation.
Key Differences from Plantar Fasciitis
It's important to differentiate tarsal tunnel syndrome from plantar fasciitis. While both affect the foot and heel, their symptoms and underlying causes differ:
| Feature | Tarsal Tunnel Syndrome | Plantar Fasciitis |
|---|---|---|
| Primary Symptom | Numbness, tingling, "pins and needles" sensation | Sharp, stabbing, or throbbing pain |
| Location | Heel, arch, toes, possibly extending to the calf | Heel (especially in the morning) |
| Cause | Nerve compression | Inflammation of the plantar fascia ligament |
Potential Causes of Tarsal Tunnel Syndrome
Several factors can contribute to tarsal tunnel syndrome:
- Overpronation: Excessive inward rolling of the foot during walking.
- Flat feet: Lack of arch support can strain the tibial nerve.
- Injuries: Ankle sprains or fractures can damage the nerve.
- Inflammatory conditions: Arthritis can cause swelling that compresses the nerve.
- Space-occupying lesions: Ganglion cysts or tumors near the tarsal tunnel.
- Improper footwear: Shoes that don't provide adequate support.
What You Can Do
If you experience heel tingling after walking, consider the following:
- Rest: Avoid activities that aggravate the tingling.
- Ice: Apply ice packs to the affected area for 15-20 minutes at a time, several times a day.
- Over-the-counter pain relievers: NSAIDs like ibuprofen or naproxen can help reduce inflammation and pain.
- Proper footwear: Wear supportive shoes with good arch support. Consider orthotics.
- Stretch and strengthen: Gentle stretching and strengthening exercises for the foot and ankle can help.
- Consult a doctor: If the tingling persists or worsens, consult a doctor or podiatrist for diagnosis and treatment. They may recommend further testing (nerve conduction studies) or treatments like corticosteroid injections, physical therapy, or surgery in severe cases.
While tarsal tunnel syndrome is the most probable cause, other nerve impingements or vascular issues could also contribute to heel tingling. Seeking professional medical advice is crucial for accurate diagnosis and appropriate treatment.
