what is this sudden bump on my heel
Whatâs that bump on the back of my heel? If youâve noticed a lump right above your heel thatâs red and sore and gets worse when you walk or run in shoes, you might have Haglundâs Deformity, also known as âpump bumpâ. Itâs remarkable how the combination of heredity and footwear can cause so many foot problems.
