Free text: Beginning about 10pm on 4/23 I developed a severe sinus type headache between my eyes as well as allvthe way around my head including the top. I felt generally awful with no energy and some dizziness. It all lasted until about 8pm on 4/24. The headache subsided and I gradually regained energy and lost most,but not all of the dizzy feelings- which have persisted thru today-4/26(11:46pm). I still feel some presure in my head,but I cant really call it pain- just a bit annoying.

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".
