When a fracture occurs, the pain can be tear-like pain, swelling pain, etc. The details are as follows: 1. Tear-like pain: When a fracture occurs, the pain is generally more intense, sometimes like tearing pain, mainly because the broken end of the fracture will damage the periosteum, which has more nerve fibers among the periosteum, so there will be severe pain. 2. Swelling pain: In the late stage of the fracture, it often occurs Localized swelling pain, mainly due to edema of the soft tissue at the fracture site and obstruction of blood return, is often a swelling pain caused by swelling of the limb. Regardless of the type of pain, the fracture must be fixed in an effective cast in the early stage, which can prevent the micro-movement of the broken end of the fracture and at the same time reduce the stimulation of the periosteum and the surrounding soft tissues, it can reduce the pain caused by the fracture.
