Occasional stabbing pain at the fracture site after walking on the ground in March after a foot or foot fracture may be caused by poor fracture healing, soft tissue injury around the fracture end and other factors. 1. Poor fracture healing: Improper treatment of fracture will lead to poor fracture healing, which will slow down the progress of fracture healing when walking on the ground with weight bearing, and damage to the surrounding muscles, fascia and other tissues, resulting in symptoms of stabbing pain. 2. Soft tissue injury around the fracture end: When playing sports, the broken end of the fracture will cause damage to the surrounding muscles, ligaments, tendons and other soft tissues, resulting in congestion and edema and other reactions. If left untreated, this can lead to occasional stabbing pain when walking on the ground. If the symptoms of stabbing pain caused by walking on the ground are obvious, it is recommended to go to the orthopedic department of the hospital to find out how the fracture is healing and to treat it accordingly.
