The causes of lateral heel pain are as follows: First, to consider peroneal tendonitis, the peroneal long and short muscles reach the sole of the foot through the intertrochanteric groove at the back of the fibula, and if there is an impingement of the peroneal tendon, it is easy to have pain in the lateral side of the heel. This kind of impingement often occurs after the heel bone fracture, the fracture is poorly aligned, the lateral wall of the heel bone protrudes outward, it is easy to impinge on the peroneal tendon, causing pain in the lateral wall of the heel bone. Secondly, if the pain occurs on the inner side of the heel bone, it is mostly seen in the inflammation of the carrier talus, for example, the carrier talus bone protrusion is more obvious, and the osteochondritis often occurs, which manifests itself as special pain in the bone protrusion on the inner side of the heel bone.
