There are days when things seem relatively manageable, and then without much warning, symptoms flare again. It might be dizziness, fatigue, brain fog, or a general sense that the body is “off,” even if nothing obvious has changed.

Some people describe it like this: “I feel like my body never fully relaxes anymore.” Others say they’re always tense, alert, or on edge—even when life is calm.

Most people think of physical training as something that only involves the body. You move, stretch, lift, or repeat exercises, and over time you get stronger or more coordinated.

Simple things like walking through a store, turning your head quickly, or stepping off a curb usually don’t require much thought. Your brain and body handle them automatically.
