Is this PEM?
I have fatigue and started working out agian after 6 months but the last 2 months I’ve walked 20,000 steps a day and feel okay I have been doing stairmaster and lifting weights to failure the last 8 days and have felt okey other than super fatigued legs randomly today at work I got horrible vertigo and had to leave work super dizzy room spinning brain fog I had never experienced anything like it before could this be PEM or unrelated
