Autoimmune fatigue feels like a deep, overwhelming exhaustion that sleep doesn't fix, marked by a heavy, whole-body tiredness, brain fog, reduced stamina for simple tasks, and muscle weakness, often accompanied by flares, joint pain, or cognitive issues, stemming from the immune system's overactivity causing inflammation that drains energy and affects the brain and muscles. It's more than just being tired; it's a profound energy depletion that makes daily life challenging.
