That painful heel bump you feel on the back of your foot is called Haglund’s deformity. It’s a bony enlargement on your heel bone caused by pressure from the backs of your shoes. The condition is also called “pump bump” because it’s common in women who wear—you guessed it—pumps. You can find the condition on the entire back of your heel or just a section. Either way, it’s most commonly found on the outside of your heel, not the bottom. Bursitis is also likely to manifest with this deformity. It occurs when a fluid-filled sac called a bursa becomes inflamed as friction and excessive pressure starts to rub over the extra bone. This is what can create most of the inflammation and swelling that will make walking painful for you. A bump on the back of your heel can really create some problems when wearing shoes. Let the experts at Premier Podiatry & Orthopedics recommend the best kind of footwear for this condition.
