Haglund’s Deformity (also known as pump bump or retrocalcaneal bursitis) is a painful enlargement on the back of the heel bone that becomes irritated by shoes. It normally appears as a red, painful, and swollen area in the back of the heel bone. Women tend to develop the condition more than men because of irritation from rigid heel counters in shoes that rub up and down on the back of the heel bone.
Changing shoes, soaking feet, and anti-inflammatory medications often mitigate the symptoms of this problem. Padding, physical therapy, injections avoiding the achilles tendon, and softer heel counters are helpful. Surgery is indicated depending on severity of symptoms and prominence of the enlargement.
