Have you ever wondered what that painful bump on the back of your heel is? It could be a blister, but more likely, it could be Haglund’s deformity.

Haglund’s deformity is an enlargement of the bone on the back of the heel. This enlargement can cause the soft tissue near the Achilles tendon to become irritated and can even then cause painful bursitis (a fluid-filled sac between the Achilles tendon and bone). When the heel becomes inflamed, calcium can build up in the heel which then makes the bump larger and increases your pain.

Haglund’s deformity can be caused by having high arches, a tight Achilles tendon, walking on the outsides of your feet, or even wearing shoes that have very rigid backs (such as, ice skates, women’s pumps, men’s dress shoes, etc.).

Symptoms of Haglund’s deformity include: a noticeable bony bump on the back of the heel, redness of the area, swelling in the bursa or severe pain at the heel.

Depending upon the severity of the condition, there are several methods of treatment:

  • Shoe modification. Wear backless or soft backed shoes to help avoid or minimize irritation.
  • Orthotic devices. Custom arch supports control the motion in the foot.
  • Heel pads. Pads placed inside the shoe cushion of the heel may help reduce irritation and pressure when walking.
  • Ice. To reduce swelling, apply an ice pack to the inflamed area for 20 minutes at a time.
  • Exercises. Stretching exercises help relieve tension from the Achilles tendon.
  • Heel lifts. Patients with high arches may find that heel lifts placed inside the shoe decrease the pressure on the heel.
  • Medication. Topical anti-inflammatory or oral non-steroidal anti-inflammatory drugs (NSAIDs), to reduce the pain and inflammation.
  • Physical therapy. Physical therapy modalities, such as an ultrasound, can help to reduce inflammation.
  • Immobilization. Wearing a boot or cast to allow the area to heal.
  • Surgery. Physical removal of the extended piece of bone.

Prevention of Haglund’s deformity is very easy. Avoid shoes with rigid backs, use orthotics (if appropriate for you), avoid running uphill or on hard surfaces like asphalt and perform stretches that keep the Achilles tendon loose.
