Whatâs that bump on the back of my heel? If youâve noticed a lump right above your heel thatâs red and sore and gets worse when you walk or run in shoes, you might have Haglundâs Deformity, also known as âpump bumpâ. Itâs remarkable how the combination of heredity and footwear can cause so many foot problems.
Heel spurs occur when calcium deposits build up on the underside of the heel bone, a process that usually occurs over a period of many months. Heel spurs are often caused by strains on foot muscles and ligaments, stretching of the plantar fascia, and repeated tearing of the membrane that covers the heel bone. Heel spurs are especially common among athletes whose activities include large amounts of running and jumping. Risk factors for heel spurs include: 1  Walking gait abnormalities,which place excessive stress on the heel bone, ligaments, and nerves near the heel. 2  Running or jogging, especially on hard surfaces. 3  Poorly fitted or badly worn shoes, especially those lacking appropriate arch support. 4  Excess weight and obesity.
