My daughter's symptoms are tic in the pediatrics department. What should I do?

This is a second-grade girl in elementary school this year.

Since last year, when the child sits on the sofa and watches TV, they seem to hiccup.

I experienced symptoms of my shoulder and body jerking, which I found abnormal, but those symptoms have not gone away.

I asked the pediatric clinic I go to, and they said it seems like a tic, so they suggested to just observe.

The child is aware of their symptoms and feels anxious while being cautious.

I just can't keep watching passively.

If there is a helpful treatment, I would like to try it. How can I proceed?
