Pump bump (Haglund's deformity)

“Pump bump,” or Haglund's deformity, is a type of bursitis of the heel. Bursitis is an inflammation of the sacs (bursae) that contain small amounts of lubricating fluid to help joints move smoothly.

A shoe rubbing on the back of the heel may cause the bump to form. The friction stimulates growth of a bone spur that then irritates the bursa. This is most often seen in women who wear high heels.

Common symptoms may include:

  • A bump on the back and outside of the heel.
  • Tenderness.
  • A callus.
  • A clicking sensation when you press on the bump.

Treatment aims to relieve shoe pressure and friction over the bump. Measures to relieve pressure include using a thick heel pad or sponge insert or switching to sandals, clogs, or shoes with a soft heel counter and no obvious seams or stitching over the ridge. Home treatment, such as massaging the area with ice and taking nonprescription anti-inflammatory medications, may help further relieve symptoms. If home treatment is not successful, surgery may be needed.
