Pain is worse from motion and sometimes improved by eating. Migraines that start with flickering in the eyes, dim vision, or dizziness suggest a need for this remedy. When this remedy is indicated, the person feels weak and lethargic, with a heavy feeling in the face and eyes, and droopy eyes with diminished vision. Pain may be mostly felt in the back of the head and muscles of the neck. The person may tremble, and sometimes heat or chills run up and down the spine.
Pain often is relieved by urinating.
Worry, fear, or dread of a stressful event may precipitate a headache. The headache is often focused on one side of the head, and may feel as if a nail is driven in. Twitching in the face or spasms in the muscles of the neck and back frequently occur. The person feels worse from resting and better from motion. When the headache begins, the person is very sensitive to light, and vision gradually diminishes.
