"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.
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, taking non-prescription anti-inflammatory medicines, and alternating between ice or a heat pack may help further relieve symptoms. If home treatment doesn't work, surgery may be needed.
