Free text: late at night, around 4:30 am, I experienced what felt like a small seizure. My muscles all tensed up uncontrollably and then violently shook for a good amount of time. I cried. I didnt have control of my limbs, and my thoughts were foggy and my mom says I spoke what sounded like gibberish at times and spoke irrationally and quickly. After the uncontrollable shaking stopped, I regained control, but still felt an urge to continue to shake my body restlessly. This might by because i just felt so tense, like my body was paralyzing.

Each entry is dated by the survey it was written in (the CDC re-sent the releases with survey dates in 2025); click a date to see that survey response. The CDC cut some text off at about 250 characters: symptoms in every release, and the other two fields in releases 9-12. Those entries are marked "cut off by CDC".
