Migraine is a chronic condition characterized by recurrent episodes of intense, throbbing head pain that can disrupt daily life. It is more than a normal headache and can last from a couple of hours to a few days. The condition typically progresses through four stages, each with distinct symptoms. Prodrome, the first stage, is when the body gives several warning signals that a migraine episode is about to occur.

These warning signs are important, yet they are often mistaken for other issues. Knowing about them can prevent a migraine from progressing, reducing pain and discomfort.

Sudden changes in mood and energy

In the days or hours before a migraine episode, in the prodrome stage, some may feel angry or easily annoyed, whereas others may feel sad or restless. At times, one may feel overly happy or euphoric. Such unexplained feelings are common. Along with these mood changes, one may have shifts in energy levels. For instance, despite adequate sleep, one may experience persistent fatigue that does not resolve. These changes are caused by fluctuations in brain chemistry and function during the prodrome stage.

Visual changes

Migraine aura refers to sensory or visual disturbances that may arise before a migraine episode. At this stage of migraine, headaches are debilitating and can disrupt daily life. One might face difficulty reading or focusing on certain texts. They might also experience flashes of light or zigzags, blind spots, tingling, or numbness. These symptoms can be accompanied by cognitive challenges, such as difficulty finding the right words in conversation (aphasia) or brain fog.

Changes in sleep

About 24 to 48 hours before the migraine episode begins, one might experience sleep disturbances. Some may find it difficult to fall asleep even when they feel tired, while others may wake up at night, have vivid dreams, or sleep far longer than usual. This happens because migraine disrupts the body’s control and release of sleep-regulating hormones.

Heightened sensitivity to light and sound

During the prodrome stage, the brain’s filtering system becomes less stable, leading to heightened sensitivity to stimuli that are typically considered normal. Some may experience photophobia, characterized by discomfort or pain from exposure to light sources, such as fluorescent lights, sunlight, and computer screens. Similarly, some may experience phonophobia, in which normal sounds, such as those caused by traffic or television sets, can feel unbearably loud or painful. The heightened sensitivity is due to hyperactivity of the trigeminal nerve, which plays an important role in how the brain processes sensory information.

Digestive changes

Changes in the digestive system are among the early signs the body gives that indicate an upcoming migraine episode. Bloating or abdominal discomfort, nausea without an apparent cause, changes in bowel movements, vomiting, and constipation are among the symptoms to watch for.

Neck stiffness and muscle tension

Some experience tension in their jaw, shoulders, and neck hours before a migraine episode. It can be a result of the brain preparing for a migraine episode and not just due to poor posture. Migraine-related muscle tension and stiffness both result from a migraine attack and drive further pain. Typically, it presents as tension in the shoulder and upper back muscles, the back and sides of the neck, the muscles around the temporal region, and the jaw muscles, which can lead to clenching of the teeth.

Recognizing these early warning signs of migraine allows one to take the necessary steps to prevent it from progressing to severe pain, reduce the episode’s overall duration, and improve one’s quality of life.
