After a patient suffers a fracture, they generally experience common symptoms associated with the injury, such as pain and swelling at the site of the fracture, which are common symptoms that can appear with all injuries. At the same time, there are some symptoms specific to fractures, which include three distinct symptoms: First, deformity, meaning the external appearance of the fracture patient will change; Second, the sound and sensation of bone rubbing, for example, after a limb fracture, the two broken ends may produce a rubbing sound or sensation; Third, abnormal movement, meaning that after the fracture, the site of the fracture will exhibit a level of mobility and range of motion that is abnormal. These are the three specific symptoms of fracture patients.
