Free text: Armpit-Still swollen and sore. Less pain today than yesterday, but swelling remains the same size. My armpit is bulging outward. And now I feel some discomfort in the surrounding area around my armpit. Almost as if the swelling and pain is spreading out and dissolving into the surrounding tissue. This included my upper rib age and breast tissue, but again, its lessening by the hour.

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".
