Girls, we went to an orthopedist today, he diagnosed us with muscle dystonia. What is that? Everyone has it? Sent us to a neurologist, he said that it doesn't get better on our legs, and we need to sit down ? We can't crawl or sit yet. We have to wait a week for a private appointment. Has anyone had this happen?
