Okay I just came across this hypothesis (longcovid patient coming up on three years). I got my levels tested and resting levels are out of range at 57 mg/dL. Got a home test kit and have been able to see fluctuations throughout the day. The thing that brings it in range is using my hyperbaric tank and/or my O2 concentrator. I feel like this should be talked about more! Lactic acidosis symptoms are exertional fatigue, brainfog, and nausea. Is this contributing to severe longcovid symptoms??
