Summary
Puffin 94896, a 34-year-old man in Missouri, developed long COVID in 2023 with daily left-side chest pain, racing heart and electric jolts that left him sedentary for three years. A cannabis gummy that triggered a seizure-like episode and a later reinfection worsened him. Supplements and medicines, metoprolol, ketotifen and avoiding triggers made him more stable, but he still had daily pain, breathlessness and oxygen dips.
