What does it feel like to break a bone ( 骨头 ) ? It’ s different for everyone, but the pain is often sharp ( 严重 ) . If the break is small, however, the person may not feel much pain at all . If you think that you or someone else has broken a bone, the most important things to do are to stay calm, make the hurt person comfortable, and call the doctor . Do not move the injured body part since movement could make it worse . To treat the break, the doctor will need to take an X-ray. This gives the doctor the information he or she needs to set ( 接上 ) the bone: to put it back to its normal place . If the bon e is large or it is broken in more than one place, the doctor may need to use metal pin s ( 钢钉 ) to set it. After the bone has been set, the next step is usually putting on a cast, the special, hard thing that will keep the bone in place for a month or two. Your bones are excellent at heal ing themselves. Broken bones will produce many new cells ( 细胞 ) and tiny blood vessels ( 血脉 ) . These cover both ends of the broken part, and close up the break until the bone is as whole and strong as before.
