What Is Myositis?
7. Juvenile Myositis
This rare form of myositis occurs in between two and four children out of a million. Age of onset is before 18 years old. There are juvenile forms of dermatomyositis and polymyositis. Of the two, JDM is more common, while JPM is extremely rare. A skin rash is typically the first symptom to appear, though muscle weakness can begin simultaneously.
Children with JM experience many of the same symptoms of weakness and increased falling incidents as adults, but there are several additional indicators. A child may voice frequent complaints of stomach aches. They can be generally moody or irritable. Children with juvenile myositis may have a difficult time raising their heads and their voices may become suddenly hoarse.
