Checkbox List with nested questions

I am working in a health insurance flow and having a hard time improving this checkbox list experience.

The thing is: a few of the items have nested questions, related to the selected disability. And if the user selects all of them, it becomes an infinite scroll on the page.

I'm trying to figure out a more "compact" way, that avoids too much scroll. And even other suggestions for these nested questions.

Any thoughts?
