Hi...., Applying ice to the affected area for 20 to 30 minutes every few hours during the first two to three days can help control pain and swelling....Rest and immobilize the affected limb.... To reduce pain and inflammation, consider an over-the-counter pain reliever.... It's important to let your child arm hang freely. ...Avoid resting your child arms and elbows on chairs, tables, pillows or inside the sleeves of clothes until the pain subsides.... Consult Orthopedician.....
