Head Tremor

Your head moves without your wanting it to. A fine, rhythmic no, sometimes a quiet yes-nod, sometimes both at once. At first it is barely visible — a delicate vibration you only notice when you look in the mirror or someone mentions it. Later it becomes more pronounced. Stronger in certain postures, sometimes quieter at rest, often more intense under stress. You sense something trembling within you — and you cannot stop it.
