Free text: Headache took 3 days to dissipate. I feel fatigue and a bit of dizziness. It gets worse by the end of the day. There are times in which I am ok, in the morning but others in which I feel pretty bad, light headed and dizzy (moderate). Enough to not feel good. Each day I improve but the level of energy is low. I feel fatigue while walking which is not normal in me.

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".
