Summary
A Reddit user in r/cfs whose labs were called normal got a B12 shot in May 2021 and had a bad reaction: two days of severe exhaustion and pain, night-time energy that turned into anxiety and insomnia, and more fatigue than their activity warranted. They were waiting on a rheumatology referral and expected months of getting nowhere with their health.
