The most common reason for pain on the inside of your heel is plantar fasciitis. However, other possibilities exist.
Here's a breakdown of potential causes:
-
Plantar Fasciitis:
- This condition involves inflammation of the plantar fascia, a thick band of tissue that runs along the bottom of your foot from your heel to your toes.
- The pain is often most intense in the morning or after periods of rest.
- It's typically described as a sharp, stabbing pain on the underside of the heel, but can radiate to the inside as well.
- Causes: Overuse, improper footwear, tight calf muscles, obesity, and high arches can contribute to plantar fasciitis.
-
Heel Spurs:
- Heel spurs are bony growths that can develop on the heel bone. While they often don't cause pain themselves, they are commonly associated with plantar fasciitis.
- If a heel spur is present and irritating the surrounding tissues, it can cause pain on the inside of the heel.
-
Tarsal Tunnel Syndrome:
- This condition occurs when the posterior tibial nerve, which runs along the inside of the ankle and heel, becomes compressed or irritated.
- Symptoms: Pain, numbness, tingling, or burning sensations can occur on the inside of the ankle and heel, and may radiate into the arch of the foot.
-
Achilles Tendonitis (Insertional):
- While Achilles tendonitis usually affects the back of the heel, insertional Achilles tendonitis, which affects the point where the Achilles tendon attaches to the heel bone, can sometimes cause pain that radiates around the heel, potentially affecting the inside.
-
Stress Fracture:
- A stress fracture in the calcaneus (heel bone) can cause pain that is localized to the heel, including the inner aspect. This is more common in athletes and people who participate in high-impact activities.
-
Bruising:
- A direct impact to the heel, or repetitive microtrauma, could result in a bruise on the bone or soft tissues, causing pain on the inside of the heel.
What to do:
- Rest: Avoid activities that aggravate the pain.
- Ice: Apply ice packs to the affected area for 15-20 minutes at a time, several times a day.
- Stretching: Gently stretch your calf muscles and plantar fascia.
- Proper Footwear: Wear shoes with good arch support and cushioning. Avoid flat shoes or walking barefoot for prolonged periods.
- See a Doctor: If your pain is severe or doesn't improve with home treatment after a few weeks, consult a doctor or podiatrist. They can properly diagnose the cause of your heel pain and recommend the appropriate treatment. This might involve physical therapy, orthotics, or, in rare cases, surgery.
