If the child’s wrist strain is mild, the local pain and swelling is not obvious, and the child is able to carry out normal activities, only a slight local pain and discomfort when moving, usually about 1 week the pain will gradually disappear. If the strain on the wrist is more serious, with significant local swelling and crying, the child may be combined with a green branch fracture or dislocation, it is recommended that a pediatric surgical visit be made to take an x-ray to examine the specific situation. In this case, the pain usually lasts for a long time and may take more than 1 month to resolve gradually. After a pediatric wrist strain, a cold compress can be applied to the injured area within 24 hours to reduce swelling and provide some analgesia. After 48 hours of the strain, appropriate hot compresses can be applied to the child’s wrist to promote local blood circulation and help reduce swelling and relieve pain.
