Calling your health care provider
Call your health care provider if your child develops uncontrollable or jerky movements, especially if the child has recently had a sore throat.
Pay careful attention to children's complaints of sore throats and get early treatment to prevent acute rheumatic fever. If there is a strong family history of rheumatic fever, be especially watchful, because your children may be more likely to develop this infection.
