My Heel Is Killing Me... It Hurts So Much... What Is It?

My Heel Is Killing Me

Heel pain is one of the most common painful conditions seen in an arthritis clinic. This article discusses the various types of problems that cause heel pain and what can be done to make the situation better.

It's estimated that more than 1 million persons in the United States suffer from heel pain at any given time.

When a patient complains of heel pain, it must be clarified by history whether the pain is in the bottom of the heel or the back of the heel because the diagnosis and treatment are very different.

Pain in the bottom of the heel is often due to plantar fasciitis (PF). The plantar fascia is a tough band of tissue that begins at the medial (inside) part of the bottom of the heel and extends forward to attach at the ball of the foot. The fascia is responsible for maintaining the normal arch. When an excessive load is placed on the fascia, pain can develop at the origin (the heel) as well as the mid-portion (arch) of the fascia.

PF can develop in anyone but is more common in certain groups such as athletes, people older than 30 years of age, and obese individuals.

PF must be distinguished from other causes of bottom of the heel pain such as nerve entrapment, atrophy of the normal heel fat pad, stress fracture of the calcaneus (heel bone), rupture of the plantar fascia, bone cyst, bone tumor, and bone infection.

The history typically describes a gradual onset of symptoms with no prior trauma. The most telling symptom is severe pain in the bottom of the heel when taking the first morning step. Patients may report difficulty walking to the bath room. The pain tends to lessen with more walking. This "first step" pain is also present during the day if the patient has been sitting for awhile, then getting up to walk.

On exam, pain is noted with pressure applied to the medial bottom of the heel. Tenderness is worsened by pointing the toes and ankle toward the head. This is because the plantar fascia is being stretched. Pain in the arch may also be present.

One in older patients should be ruled out and that is heel pad atrophy. Normally the heel has a thick feeling to it. In older patients the heel pad may lose this thickness and flatten out. The pain is located more centrally.

Another "fooler" is entrapment of the lateral plantar nerve. Pain is felt in the medial heel but may be present at rest as well. There may be weakness spreading the toes.

Fracture of the calcaneus (heelbone) causes pain at rest that is worsened with walking. Tenderness is present along the sides of the heel. Magnetic resonance imaging (MRI) can confirm the presence if fracture.

But what about "bone spurs"? The presence of a bone spur by itself means nothing. They are very common and by themselves are not a cause of pain. Some patients with inflammatory forms of arthritis such as psoriatic arthritis, ankylosing spondylitis, or Reiter's disease have a specific type of spur that should prompt further evaluation looking for systemic forms of arthritis.

Diagnostic studies such as ultrasound and magnetic resonance imaging can be used to confirm the presence of plantar fasciitis. Electromyography (EMG) may be needed to rule out lateral plantar nerve entrapment.

So how is this condition treated?

The first thing is to institute a stretching regimen. Most people with PF also have a shortened Achilles tendon and the ability to dorsiflex (point the toes up) is limited. The plantar fascia is continuous with the Achilles fascia. Stretching the plantar fascia and the Achilles decreases the tension in the plantar fascia and helps relieve inflammation.
