Free text: I had Covid in December 2020 and lost my sense of taste and smell completely for almost a month. It returned slowly but not fully. About 4 days after the first vaccine shot I developed severe phantosmia/parasomia issues. This got worse after the second dose. I either cigarette smoke (never smoke in my house... I've confirmed that it's just me), a chemical smell that gives me a headache even though no one else can smell it, or a burned rubber/plastic/trash combo smell - most food and drinks take on that same burned plastic taste as well. I had these symptoms only after the vaccine shots. Reporting this in case others are experiencing it as there is nothing being published about it-- I've searched everywhere. It's a nightmare and I'd love to know if it's a coincidence or if it's related to the vaccine. And better yet, is it a permanent thing, or the slow return of my taste and smell senses?

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".
