MRI and labwork

Today Cat had her MRI of her jaw, and that machine was the loudest I think I have ever heard. They had to to fit the machine for Catherine since she was so little, and then they had to lay her head in between two cameras. She did really good to lay still for an hour. But every time the machine turned on we jumped, it was incredibly loud. Her pediatric specialist seems to think her insomnia is coming from her asthma medication, so I need to contact that doctor. But she is still having pain and stiffness in her knee. Cat didn’t sleep good at all last night, she had a hard time going to sleep then she woke up at 3am and was wide awake until 6, went back to sleep got up at 8, and was just tired all day long. Now we both have sore throats..I don’t know what it could be.
