A three-year-old and eleven-month-old child suffered a left arm sprain on April 26, 2017, resulting in elbow pain and inability to move. After local diagnosis, no bone abnormalities were found, and only rest was recommended until May 18, 2017, when the child was admitted to Haishi Children’s Hospital for treatment.

A child’s limp may be caused by soft tissue injury, and it is recommended to undergo anti-inflammatory treatment and use blood-activating medicines while ensuring adequate rest.
