Aura jus won’t quit

Hi again, back on behalf of my kid (11F) who has been diagnosed with FND for a little over a year. Today she is experiencing what she describes as a feeling like the aura before a seizure like attack, but it won’t go away. She has tried both ignoring it and tries to let her body do it, but neither is working to get the feeling to pass. I did let her come home early from school because that sounds awful and it seemed to me like her nervous system must need a chance to rest and reset. Have others experienced this? What has helped?
