Summary
A person who developed long COVID in April 2020 with brain fog, fatigue and arthritis had a mild-to-moderate course for years, later adding gluten intolerance and IBS. A suspected reinfection in December 2025 brought dysautonomia, fainting after singing and severe anxiety, and they took leave from their weekend driving job. Low-dose naltrexone, Pepcid and compression socks helped partially; they cut LDN from 4.0 to 3.0 mg over dizziness.
